Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83178, here are decompositions:

  • 41 + 83137 = 83178
  • 61 + 83117 = 83178
  • 89 + 83089 = 83178
  • 101 + 83077 = 83178
  • 107 + 83071 = 83178
  • 131 + 83047 = 83178
  • 181 + 82997 = 83178
  • 197 + 82981 = 83178

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 83178 first appears in π at position 39,905 of the decimal expansion (the 39,905ordinal-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.
