Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487998, here are decompositions:

  • 67 + 2147487931 = 2147487998
  • 127 + 2147487871 = 2147487998
  • 181 + 2147487817 = 2147487998
  • 199 + 2147487799 = 2147487998
  • 241 + 2147487757 = 2147487998
  • 307 + 2147487691 = 2147487998
  • 349 + 2147487649 = 2147487998
  • 457 + 2147487541 = 2147487998

Showing the first eight; more decompositions exist.
