Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78066, here are decompositions:

  • 7 + 78059 = 78066
  • 17 + 78049 = 78066
  • 59 + 78007 = 78066
  • 67 + 77999 = 78066
  • 83 + 77983 = 78066
  • 89 + 77977 = 78066
  • 97 + 77969 = 78066
  • 137 + 77929 = 78066

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78066 first appears in π at position 31,600 of the decimal expansion (the 31,600ordinal-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.
