Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85668, here are decompositions:

  • 7 + 85661 = 85668
  • 29 + 85639 = 85668
  • 41 + 85627 = 85668
  • 47 + 85621 = 85668
  • 61 + 85607 = 85668
  • 67 + 85601 = 85668
  • 71 + 85597 = 85668
  • 97 + 85571 = 85668

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85668 first appears in π at position 154,899 of the decimal expansion (the 154,899ordinal-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.
