Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510598, here are decompositions:

  • 37 + 31510561 = 31510598
  • 109 + 31510489 = 31510598
  • 139 + 31510459 = 31510598
  • 151 + 31510447 = 31510598
  • 199 + 31510399 = 31510598
  • 211 + 31510387 = 31510598
  • 277 + 31510321 = 31510598
  • 487 + 31510111 = 31510598

Showing the first eight; more decompositions exist.
