Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469048, here are decompositions:

  • 7 + 2147469041 = 2147469048
  • 31 + 2147469017 = 2147469048
  • 41 + 2147469007 = 2147469048
  • 47 + 2147469001 = 2147469048
  • 61 + 2147468987 = 2147469048
  • 139 + 2147468909 = 2147469048
  • 167 + 2147468881 = 2147469048
  • 239 + 2147468809 = 2147469048

Showing the first eight; more decompositions exist.
