Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86970, here are decompositions:

  • 11 + 86959 = 86970
  • 19 + 86951 = 86970
  • 31 + 86939 = 86970
  • 41 + 86929 = 86970
  • 43 + 86927 = 86970
  • 47 + 86923 = 86970
  • 101 + 86869 = 86970
  • 109 + 86861 = 86970

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86970 first appears in π at position 179,356 of the decimal expansion (the 179,356ordinal-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.
