Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17178, here are decompositions:

  • 11 + 17167 = 17178
  • 19 + 17159 = 17178
  • 41 + 17137 = 17178
  • 61 + 17117 = 17178
  • 71 + 17107 = 17178
  • 79 + 17099 = 17178
  • 101 + 17077 = 17178
  • 131 + 17047 = 17178

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17178 first appears in π at position 104,828 of the decimal expansion (the 104,828ordinal-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.
