Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539466, here are decompositions:

  • 53 + 31539413 = 31539466
  • 89 + 31539377 = 31539466
  • 113 + 31539353 = 31539466
  • 137 + 31539329 = 31539466
  • 383 + 31539083 = 31539466
  • 419 + 31539047 = 31539466
  • 479 + 31538987 = 31539466
  • 659 + 31538807 = 31539466

Showing the first eight; more decompositions exist.
