Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584590, here are decompositions:

  • 13 + 31584577 = 31584590
  • 31 + 31584559 = 31584590
  • 43 + 31584547 = 31584590
  • 67 + 31584523 = 31584590
  • 109 + 31584481 = 31584590
  • 151 + 31584439 = 31584590
  • 229 + 31584361 = 31584590
  • 283 + 31584307 = 31584590

Showing the first eight; more decompositions exist.
