Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536628, here are decompositions:

  • 89 + 31536539 = 31536628
  • 107 + 31536521 = 31536628
  • 269 + 31536359 = 31536628
  • 281 + 31536347 = 31536628
  • 401 + 31536227 = 31536628
  • 467 + 31536161 = 31536628
  • 647 + 31535981 = 31536628
  • 719 + 31535909 = 31536628

Showing the first eight; more decompositions exist.
