Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473656, here are decompositions:

  • 89 + 2147473567 = 2147473656
  • 103 + 2147473553 = 2147473656
  • 173 + 2147473483 = 2147473656
  • 179 + 2147473477 = 2147473656
  • 227 + 2147473429 = 2147473656
  • 283 + 2147473373 = 2147473656
  • 359 + 2147473297 = 2147473656
  • 373 + 2147473283 = 2147473656

Showing the first eight; more decompositions exist.
