Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541832, here are decompositions:

  • 5 + 31541827 = 31541832
  • 71 + 31541761 = 31541832
  • 139 + 31541693 = 31541832
  • 173 + 31541659 = 31541832
  • 181 + 31541651 = 31541832
  • 199 + 31541633 = 31541832
  • 241 + 31541591 = 31541832
  • 251 + 31541581 = 31541832

Showing the first eight; more decompositions exist.
