Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40480, here are decompositions:

  • 47 + 40433 = 40480
  • 53 + 40427 = 40480
  • 137 + 40343 = 40480
  • 191 + 40289 = 40480
  • 197 + 40283 = 40480
  • 227 + 40253 = 40480
  • 239 + 40241 = 40480
  • 311 + 40169 = 40480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40480 first appears in π at position 58,303 of the decimal expansion (the 58,303ordinal-suffix:rd 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.
