Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470646, here are decompositions:

  • 3 + 2147470643 = 2147470646
  • 19 + 2147470627 = 2147470646
  • 43 + 2147470603 = 2147470646
  • 67 + 2147470579 = 2147470646
  • 193 + 2147470453 = 2147470646
  • 313 + 2147470333 = 2147470646
  • 397 + 2147470249 = 2147470646
  • 463 + 2147470183 = 2147470646

Showing the first eight; more decompositions exist.
