Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512348, here are decompositions:

  • 5 + 31512343 = 31512348
  • 17 + 31512331 = 31512348
  • 41 + 31512307 = 31512348
  • 59 + 31512289 = 31512348
  • 89 + 31512259 = 31512348
  • 137 + 31512211 = 31512348
  • 139 + 31512209 = 31512348
  • 149 + 31512199 = 31512348

Showing the first eight; more decompositions exist.
