Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3580, here are decompositions:

  • 23 + 3557 = 3580
  • 41 + 3539 = 3580
  • 47 + 3533 = 3580
  • 53 + 3527 = 3580
  • 89 + 3491 = 3580
  • 113 + 3467 = 3580
  • 131 + 3449 = 3580
  • 167 + 3413 = 3580

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3580 first appears in π at position 4,319 of the decimal expansion (the 4,319ordinal-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.
