Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532832, here are decompositions:

  • 83 + 31532749 = 31532832
  • 139 + 31532693 = 31532832
  • 173 + 31532659 = 31532832
  • 179 + 31532653 = 31532832
  • 193 + 31532639 = 31532832
  • 239 + 31532593 = 31532832
  • 251 + 31532581 = 31532832
  • 281 + 31532551 = 31532832

Showing the first eight; more decompositions exist.
