Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522386, here are decompositions:

  • 13 + 31522373 = 31522386
  • 23 + 31522363 = 31522386
  • 29 + 31522357 = 31522386
  • 47 + 31522339 = 31522386
  • 59 + 31522327 = 31522386
  • 73 + 31522313 = 31522386
  • 89 + 31522297 = 31522386
  • 109 + 31522277 = 31522386

Showing the first eight; more decompositions exist.
