Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18546, here are decompositions:

  • 5 + 18541 = 18546
  • 7 + 18539 = 18546
  • 23 + 18523 = 18546
  • 29 + 18517 = 18546
  • 43 + 18503 = 18546
  • 53 + 18493 = 18546
  • 89 + 18457 = 18546
  • 103 + 18443 = 18546

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18546 first appears in π at position 88,539 of the decimal expansion (the 88,539ordinal-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.
