Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539632, here are decompositions:

  • 109 + 31539523 = 31539632
  • 193 + 31539439 = 31539632
  • 211 + 31539421 = 31539632
  • 283 + 31539349 = 31539632
  • 349 + 31539283 = 31539632
  • 571 + 31539061 = 31539632
  • 853 + 31538779 = 31539632
  • 919 + 31538713 = 31539632

Showing the first eight; more decompositions exist.
