Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45378, here are decompositions:

  • 17 + 45361 = 45378
  • 37 + 45341 = 45378
  • 41 + 45337 = 45378
  • 59 + 45319 = 45378
  • 61 + 45317 = 45378
  • 71 + 45307 = 45378
  • 89 + 45289 = 45378
  • 97 + 45281 = 45378

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45378 first appears in π at position 55,182 of the decimal expansion (the 55,182ordinal-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.
