Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521264, here are decompositions:

  • 13 + 521251 = 521264
  • 97 + 521167 = 521264
  • 103 + 521161 = 521264
  • 127 + 521137 = 521264
  • 157 + 521107 = 521264
  • 223 + 521041 = 521264
  • 241 + 521023 = 521264
  • 283 + 520981 = 521264

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 521,264 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 521264 first appears in π at position 549,909 of the decimal expansion (the 549,909ordinal-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.
