Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530218, here are decompositions:

  • 7 + 31530211 = 31530218
  • 37 + 31530181 = 31530218
  • 157 + 31530061 = 31530218
  • 241 + 31529977 = 31530218
  • 337 + 31529881 = 31530218
  • 541 + 31529677 = 31530218
  • 547 + 31529671 = 31530218
  • 661 + 31529557 = 31530218

Showing the first eight; more decompositions exist.
