Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468236, here are decompositions:

  • 3 + 2147468233 = 2147468236
  • 5 + 2147468231 = 2147468236
  • 47 + 2147468189 = 2147468236
  • 167 + 2147468069 = 2147468236
  • 233 + 2147468003 = 2147468236
  • 269 + 2147467967 = 2147468236
  • 317 + 2147467919 = 2147468236
  • 443 + 2147467793 = 2147468236

Showing the first eight; more decompositions exist.
