Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545022, here are decompositions:

  • 53 + 31544969 = 31545022
  • 59 + 31544963 = 31545022
  • 239 + 31544783 = 31545022
  • 251 + 31544771 = 31545022
  • 263 + 31544759 = 31545022
  • 449 + 31544573 = 31545022
  • 461 + 31544561 = 31545022
  • 479 + 31544543 = 31545022

Showing the first eight; more decompositions exist.
