Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469128, here are decompositions:

  • 61 + 2147469067 = 2147469128
  • 127 + 2147469001 = 2147469128
  • 157 + 2147468971 = 2147469128
  • 241 + 2147468887 = 2147469128
  • 349 + 2147468779 = 2147469128
  • 631 + 2147468497 = 2147469128
  • 787 + 2147468341 = 2147469128
  • 811 + 2147468317 = 2147469128

Showing the first eight; more decompositions exist.
