Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40372, here are decompositions:

  • 11 + 40361 = 40372
  • 29 + 40343 = 40372
  • 83 + 40289 = 40372
  • 89 + 40283 = 40372
  • 131 + 40241 = 40372
  • 179 + 40193 = 40372
  • 359 + 40013 = 40372
  • 383 + 39989 = 40372

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40372 first appears in π at position 120,368 of the decimal expansion (the 120,368ordinal-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.
