Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521632, here are decompositions:

  • 29 + 521603 = 521632
  • 113 + 521519 = 521632
  • 149 + 521483 = 521632
  • 233 + 521399 = 521632
  • 239 + 521393 = 521632
  • 263 + 521369 = 521632
  • 269 + 521363 = 521632
  • 389 + 521243 = 521632

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 521,632 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 521632 first appears in π at position 9,190 of the decimal expansion (the 9,190ordinal-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.
