Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521882, here are decompositions:

  • 3 + 521879 = 521882
  • 13 + 521869 = 521882
  • 73 + 521809 = 521882
  • 139 + 521743 = 521882
  • 211 + 521671 = 521882
  • 223 + 521659 = 521882
  • 241 + 521641 = 521882
  • 331 + 521551 = 521882

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 521,882 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 521882 first appears in π at position 223,156 of the decimal expansion (the 223,156ordinal-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.
