Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520158, here are decompositions:

  • 7 + 520151 = 520158
  • 29 + 520129 = 520158
  • 47 + 520111 = 520158
  • 127 + 520031 = 520158
  • 137 + 520021 = 520158
  • 139 + 520019 = 520158
  • 211 + 519947 = 520158
  • 227 + 519931 = 520158

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 520,158 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 520158 first appears in π at position 455,672 of the decimal expansion (the 455,672ordinal-suffix:nd 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.
