Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547514, here are decompositions:

  • 7 + 31547507 = 31547514
  • 43 + 31547471 = 31547514
  • 73 + 31547441 = 31547514
  • 101 + 31547413 = 31547514
  • 157 + 31547357 = 31547514
  • 197 + 31547317 = 31547514
  • 211 + 31547303 = 31547514
  • 227 + 31547287 = 31547514

Showing the first eight; more decompositions exist.
