Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468688, here are decompositions:

  • 37 + 2147468651 = 2147468688
  • 67 + 2147468621 = 2147468688
  • 89 + 2147468599 = 2147468688
  • 97 + 2147468591 = 2147468688
  • 151 + 2147468537 = 2147468688
  • 181 + 2147468507 = 2147468688
  • 191 + 2147468497 = 2147468688
  • 257 + 2147468431 = 2147468688

Showing the first eight; more decompositions exist.
