Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468990, here are decompositions:

  • 3 + 2147468987 = 2147468990
  • 19 + 2147468971 = 2147468990
  • 67 + 2147468923 = 2147468990
  • 103 + 2147468887 = 2147468990
  • 109 + 2147468881 = 2147468990
  • 157 + 2147468833 = 2147468990
  • 181 + 2147468809 = 2147468990
  • 211 + 2147468779 = 2147468990

Showing the first eight; more decompositions exist.
