Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545468, here are decompositions:

  • 29 + 31545439 = 31545468
  • 61 + 31545407 = 31545468
  • 67 + 31545401 = 31545468
  • 89 + 31545379 = 31545468
  • 137 + 31545331 = 31545468
  • 139 + 31545329 = 31545468
  • 151 + 31545317 = 31545468
  • 181 + 31545287 = 31545468

Showing the first eight; more decompositions exist.
