Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526500, here are decompositions:

  • 17 + 526483 = 526500
  • 41 + 526459 = 526500
  • 47 + 526453 = 526500
  • 59 + 526441 = 526500
  • 71 + 526429 = 526500
  • 103 + 526397 = 526500
  • 109 + 526391 = 526500
  • 113 + 526387 = 526500

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 526,500 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 526500 first appears in π at position 816,104 of the decimal expansion (the 816,104ordinal-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.
