Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515374, here are decompositions:

  • 3 + 515371 = 515374
  • 5 + 515369 = 515374
  • 17 + 515357 = 515374
  • 23 + 515351 = 515374
  • 137 + 515237 = 515374
  • 263 + 515111 = 515374
  • 521 + 514853 = 515374
  • 617 + 514757 = 515374

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 515,374 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 515374 first appears in π at position 407,504 of the decimal expansion (the 407,504ordinal-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.
