Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483994, here are decompositions:

  • 13 + 31483981 = 31483994
  • 37 + 31483957 = 31483994
  • 67 + 31483927 = 31483994
  • 193 + 31483801 = 31483994
  • 271 + 31483723 = 31483994
  • 331 + 31483663 = 31483994
  • 397 + 31483597 = 31483994
  • 523 + 31483471 = 31483994

Showing the first eight; more decompositions exist.
