Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526480, here are decompositions:

  • 83 + 526397 = 526480
  • 89 + 526391 = 526480
  • 107 + 526373 = 526480
  • 113 + 526367 = 526480
  • 173 + 526307 = 526480
  • 191 + 526289 = 526480
  • 197 + 526283 = 526480
  • 257 + 526223 = 526480

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 526,480 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 526480 first appears in π at position 18,733 of the decimal expansion (the 18,733ordinal-suffix:rd 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.
