Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19526, here are decompositions:

  • 19 + 19507 = 19526
  • 37 + 19489 = 19526
  • 43 + 19483 = 19526
  • 79 + 19447 = 19526
  • 97 + 19429 = 19526
  • 103 + 19423 = 19526
  • 109 + 19417 = 19526
  • 139 + 19387 = 19526

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19526 first appears in π at position 47,634 of the decimal expansion (the 47,634ordinal-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.
