Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521452, here are decompositions:

  • 5 + 521447 = 521452
  • 23 + 521429 = 521452
  • 53 + 521399 = 521452
  • 59 + 521393 = 521452
  • 83 + 521369 = 521452
  • 89 + 521363 = 521452
  • 251 + 521201 = 521452
  • 389 + 521063 = 521452

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 521,452 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 521452 first appears in π at position 636,915 of the decimal expansion (the 636,915ordinal-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.
