Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19976, here are decompositions:

  • 3 + 19973 = 19976
  • 13 + 19963 = 19976
  • 109 + 19867 = 19976
  • 157 + 19819 = 19976
  • 163 + 19813 = 19976
  • 199 + 19777 = 19976
  • 223 + 19753 = 19976
  • 277 + 19699 = 19976

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19976 first appears in π at position 78,899 of the decimal expansion (the 78,899ordinal-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.
