Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76870, here are decompositions:

  • 23 + 76847 = 76870
  • 41 + 76829 = 76870
  • 89 + 76781 = 76870
  • 113 + 76757 = 76870
  • 137 + 76733 = 76870
  • 173 + 76697 = 76870
  • 191 + 76679 = 76870
  • 197 + 76673 = 76870

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 76870 first appears in π at position 111,751 of the decimal expansion (the 111,751ordinal-suffix:st 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.
