Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468118, here are decompositions:

  • 151 + 2147467967 = 2147468118
  • 197 + 2147467921 = 2147468118
  • 199 + 2147467919 = 2147468118
  • 317 + 2147467801 = 2147468118
  • 349 + 2147467769 = 2147468118
  • 359 + 2147467759 = 2147468118
  • 401 + 2147467717 = 2147468118
  • 421 + 2147467697 = 2147468118

Showing the first eight; more decompositions exist.
