Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40448, here are decompositions:

  • 19 + 40429 = 40448
  • 61 + 40387 = 40448
  • 97 + 40351 = 40448
  • 211 + 40237 = 40448
  • 271 + 40177 = 40448
  • 337 + 40111 = 40448
  • 349 + 40099 = 40448
  • 409 + 40039 = 40448

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40448 first appears in π at position 155,982 of the decimal expansion (the 155,982ordinal-suffix:nd 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.
