Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741920, here are decompositions:

  • 53 + 8741867 = 8741920
  • 59 + 8741861 = 8741920
  • 107 + 8741813 = 8741920
  • 167 + 8741753 = 8741920
  • 179 + 8741741 = 8741920
  • 233 + 8741687 = 8741920
  • 281 + 8741639 = 8741920
  • 311 + 8741609 = 8741920

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 8,741,920 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 8741920 first appears in π at position 788,899 of the decimal expansion (the 788,899ordinal-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.
