Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515342, here are decompositions:

  • 19 + 515323 = 515342
  • 31 + 515311 = 515342
  • 109 + 515233 = 515342
  • 151 + 515191 = 515342
  • 193 + 515149 = 515342
  • 199 + 515143 = 515342
  • 409 + 514933 = 515342
  • 439 + 514903 = 515342

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 515,342 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 515342 first appears in π at position 417,195 of the decimal expansion (the 417,195ordinal-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.
