Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449476, here are decompositions:

  • 13 + 31449463 = 31449476
  • 67 + 31449409 = 31449476
  • 73 + 31449403 = 31449476
  • 103 + 31449373 = 31449476
  • 229 + 31449247 = 31449476
  • 313 + 31449163 = 31449476
  • 349 + 31449127 = 31449476
  • 433 + 31449043 = 31449476

Showing the first eight; more decompositions exist.
