Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515146, here are decompositions:

  • 3 + 515143 = 515146
  • 59 + 515087 = 515146
  • 179 + 514967 = 515146
  • 197 + 514949 = 515146
  • 257 + 514889 = 515146
  • 293 + 514853 = 515146
  • 353 + 514793 = 515146
  • 389 + 514757 = 515146

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 515,146 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 515146 first appears in π at position 734,569 of the decimal expansion (the 734,569ordinal-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.
