Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7956, here are decompositions:

  • 5 + 7951 = 7956
  • 7 + 7949 = 7956
  • 19 + 7937 = 7956
  • 23 + 7933 = 7956
  • 29 + 7927 = 7956
  • 37 + 7919 = 7956
  • 73 + 7883 = 7956
  • 79 + 7877 = 7956

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7956 first appears in π at position 15,213 of the decimal expansion (the 15,213ordinal-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.
