Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469086, here are decompositions:

  • 13 + 2147469073 = 2147469086
  • 19 + 2147469067 = 2147469086
  • 79 + 2147469007 = 2147469086
  • 163 + 2147468923 = 2147469086
  • 199 + 2147468887 = 2147469086
  • 277 + 2147468809 = 2147469086
  • 283 + 2147468803 = 2147469086
  • 307 + 2147468779 = 2147469086

Showing the first eight; more decompositions exist.
