Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7936, here are decompositions:

  • 3 + 7933 = 7936
  • 17 + 7919 = 7936
  • 29 + 7907 = 7936
  • 53 + 7883 = 7936
  • 59 + 7877 = 7936
  • 83 + 7853 = 7936
  • 107 + 7829 = 7936
  • 113 + 7823 = 7936

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7936 first appears in π at position 9,768 of the decimal expansion (the 9,768ordinal-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.
