Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468958, here are decompositions:

  • 71 + 2147468887 = 2147468958
  • 97 + 2147468861 = 2147468958
  • 149 + 2147468809 = 2147468958
  • 157 + 2147468801 = 2147468958
  • 179 + 2147468779 = 2147468958
  • 241 + 2147468717 = 2147468958
  • 307 + 2147468651 = 2147468958
  • 337 + 2147468621 = 2147468958

Showing the first eight; more decompositions exist.
