Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26778, here are decompositions:

  • 19 + 26759 = 26778
  • 41 + 26737 = 26778
  • 47 + 26731 = 26778
  • 61 + 26717 = 26778
  • 67 + 26711 = 26778
  • 79 + 26699 = 26778
  • 97 + 26681 = 26778
  • 109 + 26669 = 26778

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26778 first appears in π at position 73,035 of the decimal expansion (the 73,035ordinal-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.
