Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40586, here are decompositions:

  • 3 + 40583 = 40586
  • 43 + 40543 = 40586
  • 67 + 40519 = 40586
  • 79 + 40507 = 40586
  • 103 + 40483 = 40586
  • 127 + 40459 = 40586
  • 157 + 40429 = 40586
  • 163 + 40423 = 40586

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40586 first appears in π at position 45,771 of the decimal expansion (the 45,771ordinal-suffix:st 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.
