Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625912, here are decompositions:

  • 139 + 31625773 = 31625912
  • 151 + 31625761 = 31625912
  • 181 + 31625731 = 31625912
  • 313 + 31625599 = 31625912
  • 349 + 31625563 = 31625912
  • 631 + 31625281 = 31625912
  • 733 + 31625179 = 31625912
  • 853 + 31625059 = 31625912

Showing the first eight; more decompositions exist.
