Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521270, here are decompositions:

  • 3 + 521267 = 521270
  • 19 + 521251 = 521270
  • 97 + 521173 = 521270
  • 103 + 521167 = 521270
  • 109 + 521161 = 521270
  • 151 + 521119 = 521270
  • 163 + 521107 = 521270
  • 223 + 521047 = 521270

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 521,270 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 521270 first appears in π at position 442,350 of the decimal expansion (the 442,350ordinal-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.
