Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468898, here are decompositions:

  • 11 + 2147468887 = 2147468898
  • 17 + 2147468881 = 2147468898
  • 37 + 2147468861 = 2147468898
  • 89 + 2147468809 = 2147468898
  • 97 + 2147468801 = 2147468898
  • 181 + 2147468717 = 2147468898
  • 277 + 2147468621 = 2147468898
  • 307 + 2147468591 = 2147468898

Showing the first eight; more decompositions exist.
