Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492232, here are decompositions:

  • 19 + 31492213 = 31492232
  • 139 + 31492093 = 31492232
  • 151 + 31492081 = 31492232
  • 181 + 31492051 = 31492232
  • 199 + 31492033 = 31492232
  • 439 + 31491793 = 31492232
  • 571 + 31491661 = 31492232
  • 613 + 31491619 = 31492232

Showing the first eight; more decompositions exist.
