Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520972, here are decompositions:

  • 3 + 520969 = 520972
  • 5 + 520967 = 520972
  • 29 + 520943 = 520972
  • 59 + 520913 = 520972
  • 83 + 520889 = 520972
  • 131 + 520841 = 520972
  • 251 + 520721 = 520972
  • 269 + 520703 = 520972

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 520,972 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 520972 first appears in π at position 987,442 of the decimal expansion (the 987,442ordinal-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.
