Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520822, here are decompositions:

  • 61 + 31520761 = 31520822
  • 103 + 31520719 = 31520822
  • 163 + 31520659 = 31520822
  • 241 + 31520581 = 31520822
  • 313 + 31520509 = 31520822
  • 331 + 31520491 = 31520822
  • 433 + 31520389 = 31520822
  • 523 + 31520299 = 31520822

Showing the first eight; more decompositions exist.
