Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454590, here are decompositions:

  • 3 + 31454587 = 31454590
  • 107 + 31454483 = 31454590
  • 149 + 31454441 = 31454590
  • 239 + 31454351 = 31454590
  • 269 + 31454321 = 31454590
  • 389 + 31454201 = 31454590
  • 443 + 31454147 = 31454590
  • 467 + 31454123 = 31454590

Showing the first eight; more decompositions exist.
