Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78736, here are decompositions:

  • 23 + 78713 = 78736
  • 29 + 78707 = 78736
  • 83 + 78653 = 78736
  • 113 + 78623 = 78736
  • 167 + 78569 = 78736
  • 197 + 78539 = 78736
  • 227 + 78509 = 78736
  • 239 + 78497 = 78736

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78736 first appears in π at position 10,153 of the decimal expansion (the 10,153ordinal-suffix:rd 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.
