Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523140, here are decompositions:

  • 11 + 523129 = 523140
  • 31 + 523109 = 523140
  • 43 + 523097 = 523140
  • 47 + 523093 = 523140
  • 109 + 523031 = 523140
  • 151 + 522989 = 523140
  • 179 + 522961 = 523140
  • 181 + 522959 = 523140

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 523,140 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 523140 first appears in π at position 58,544 of the decimal expansion (the 58,544ordinal-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.
