Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468528, here are decompositions:

  • 31 + 2147468497 = 2147468528
  • 97 + 2147468431 = 2147468528
  • 211 + 2147468317 = 2147468528
  • 397 + 2147468131 = 2147468528
  • 409 + 2147468119 = 2147468528
  • 607 + 2147467921 = 2147468528
  • 727 + 2147467801 = 2147468528
  • 769 + 2147467759 = 2147468528

Showing the first eight; more decompositions exist.
