Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480486, here are decompositions:

  • 53 + 31480433 = 31480486
  • 113 + 31480373 = 31480486
  • 137 + 31480349 = 31480486
  • 197 + 31480289 = 31480486
  • 227 + 31480259 = 31480486
  • 383 + 31480103 = 31480486
  • 467 + 31480019 = 31480486
  • 683 + 31479803 = 31480486

Showing the first eight; more decompositions exist.
