Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515184, here are decompositions:

  • 11 + 515173 = 515184
  • 31 + 515153 = 515184
  • 41 + 515143 = 515184
  • 73 + 515111 = 515184
  • 97 + 515087 = 515184
  • 251 + 514933 = 515184
  • 281 + 514903 = 515184
  • 311 + 514873 = 515184

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 515,184 and was likely granted around 1894.

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

Position in π

The digit sequence 515184 first appears in π at position 283,500 of the decimal expansion (the 283,500ordinal-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.
