Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18926, here are decompositions:

  • 7 + 18919 = 18926
  • 13 + 18913 = 18926
  • 67 + 18859 = 18926
  • 139 + 18787 = 18926
  • 373 + 18553 = 18926
  • 409 + 18517 = 18926
  • 433 + 18493 = 18926
  • 487 + 18439 = 18926

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18926 first appears in π at position 51,029 of the decimal expansion (the 51,029ordinal-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.
