Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584464, here are decompositions:

  • 7 + 2147584457 = 2147584464
  • 71 + 2147584393 = 2147584464
  • 73 + 2147584391 = 2147584464
  • 211 + 2147584253 = 2147584464
  • 283 + 2147584181 = 2147584464
  • 307 + 2147584157 = 2147584464
  • 401 + 2147584063 = 2147584464
  • 503 + 2147583961 = 2147584464

Showing the first eight; more decompositions exist.
