Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7958, here are decompositions:

  • 7 + 7951 = 7958
  • 31 + 7927 = 7958
  • 79 + 7879 = 7958
  • 199 + 7759 = 7958
  • 241 + 7717 = 7958
  • 271 + 7687 = 7958
  • 277 + 7681 = 7958
  • 337 + 7621 = 7958

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7958 first appears in π at position 11,838 of the decimal expansion (the 11,838ordinal-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.
