Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445598, here are decompositions:

  • 11 + 31445587 = 31445598
  • 59 + 31445539 = 31445598
  • 109 + 31445489 = 31445598
  • 139 + 31445459 = 31445598
  • 167 + 31445431 = 31445598
  • 179 + 31445419 = 31445598
  • 181 + 31445417 = 31445598
  • 211 + 31445387 = 31445598

Showing the first eight; more decompositions exist.
