Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468976, here are decompositions:

  • 5 + 2147468971 = 2147468976
  • 43 + 2147468933 = 2147468976
  • 53 + 2147468923 = 2147468976
  • 67 + 2147468909 = 2147468976
  • 89 + 2147468887 = 2147468976
  • 167 + 2147468809 = 2147468976
  • 173 + 2147468803 = 2147468976
  • 193 + 2147468783 = 2147468976

Showing the first eight; more decompositions exist.
