Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469188, here are decompositions:

  • 31 + 2147469157 = 2147469188
  • 181 + 2147469007 = 2147469188
  • 307 + 2147468881 = 2147469188
  • 379 + 2147468809 = 2147469188
  • 409 + 2147468779 = 2147469188
  • 691 + 2147468497 = 2147469188
  • 757 + 2147468431 = 2147469188
  • 919 + 2147468269 = 2147469188

Showing the first eight; more decompositions exist.
