Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85228, here are decompositions:

  • 5 + 85223 = 85228
  • 29 + 85199 = 85228
  • 107 + 85121 = 85228
  • 137 + 85091 = 85228
  • 167 + 85061 = 85228
  • 179 + 85049 = 85228
  • 191 + 85037 = 85228
  • 251 + 84977 = 85228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85228 first appears in π at position 161,152 of the decimal expansion (the 161,152ordinal-suffix:nd 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.
