Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465586, here are decompositions:

  • 7 + 31465579 = 31465586
  • 127 + 31465459 = 31465586
  • 223 + 31465363 = 31465586
  • 277 + 31465309 = 31465586
  • 409 + 31465177 = 31465586
  • 433 + 31465153 = 31465586
  • 457 + 31465129 = 31465586
  • 463 + 31465123 = 31465586

Showing the first eight; more decompositions exist.
