Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85158, here are decompositions:

  • 11 + 85147 = 85158
  • 37 + 85121 = 85158
  • 67 + 85091 = 85158
  • 71 + 85087 = 85158
  • 97 + 85061 = 85158
  • 109 + 85049 = 85158
  • 131 + 85027 = 85158
  • 137 + 85021 = 85158

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85158 first appears in π at position 83,505 of the decimal expansion (the 83,505ordinal-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.
