Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468624, here are decompositions:

  • 3 + 2147468621 = 2147468624
  • 61 + 2147468563 = 2147468624
  • 127 + 2147468497 = 2147468624
  • 181 + 2147468443 = 2147468624
  • 193 + 2147468431 = 2147468624
  • 283 + 2147468341 = 2147468624
  • 307 + 2147468317 = 2147468624
  • 661 + 2147467963 = 2147468624

Showing the first eight; more decompositions exist.
