Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40066, here are decompositions:

  • 3 + 40063 = 40066
  • 29 + 40037 = 40066
  • 53 + 40013 = 40066
  • 83 + 39983 = 40066
  • 113 + 39953 = 40066
  • 137 + 39929 = 40066
  • 179 + 39887 = 40066
  • 197 + 39869 = 40066

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40066 first appears in π at position 6,837 of the decimal expansion (the 6,837ordinal-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.
