Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85838, here are decompositions:

  • 7 + 85831 = 85838
  • 19 + 85819 = 85838
  • 127 + 85711 = 85838
  • 199 + 85639 = 85838
  • 211 + 85627 = 85838
  • 241 + 85597 = 85838
  • 307 + 85531 = 85838
  • 409 + 85429 = 85838

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85838 first appears in π at position 2,155 of the decimal expansion (the 2,155ordinal-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.
