Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17730, here are decompositions:

  • 17 + 17713 = 17730
  • 23 + 17707 = 17730
  • 47 + 17683 = 17730
  • 61 + 17669 = 17730
  • 71 + 17659 = 17730
  • 73 + 17657 = 17730
  • 103 + 17627 = 17730
  • 107 + 17623 = 17730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17730 first appears in π at position 88,154 of the decimal expansion (the 88,154ordinal-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.
