Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85018, here are decompositions:

  • 41 + 84977 = 85018
  • 71 + 84947 = 85018
  • 149 + 84869 = 85018
  • 191 + 84827 = 85018
  • 257 + 84761 = 85018
  • 281 + 84737 = 85018
  • 317 + 84701 = 85018
  • 359 + 84659 = 85018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85018 first appears in π at position 18,443 of the decimal expansion (the 18,443ordinal-suffix:rd 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.
