Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483156, here are decompositions:

  • 59 + 31483097 = 31483156
  • 179 + 31482977 = 31483156
  • 317 + 31482839 = 31483156
  • 449 + 31482707 = 31483156
  • 557 + 31482599 = 31483156
  • 569 + 31482587 = 31483156
  • 587 + 31482569 = 31483156
  • 647 + 31482509 = 31483156

Showing the first eight; more decompositions exist.
