Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512490, here are decompositions:

  • 23 + 512467 = 512490
  • 47 + 512443 = 512490
  • 61 + 512429 = 512490
  • 71 + 512419 = 512490
  • 101 + 512389 = 512490
  • 137 + 512353 = 512490
  • 157 + 512333 = 512490
  • 179 + 512311 = 512490

Showing the first eight; more decompositions exist.
