Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512416, here are decompositions:

  • 7 + 31512409 = 31512416
  • 73 + 31512343 = 31512416
  • 109 + 31512307 = 31512416
  • 127 + 31512289 = 31512416
  • 157 + 31512259 = 31512416
  • 163 + 31512253 = 31512416
  • 307 + 31512109 = 31512416
  • 379 + 31512037 = 31512416

Showing the first eight; more decompositions exist.
