Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742184, here are decompositions:

  • 23 + 8742161 = 8742184
  • 107 + 8742077 = 8742184
  • 173 + 8742011 = 8742184
  • 197 + 8741987 = 8742184
  • 233 + 8741951 = 8742184
  • 251 + 8741933 = 8742184
  • 317 + 8741867 = 8742184
  • 383 + 8741801 = 8742184

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,742,184 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8742184 first appears in π at position 146,150 of the decimal expansion (the 146,150ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
