Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443108, here are decompositions:

  • 59 + 2147443049 = 2147443108
  • 131 + 2147442977 = 2147443108
  • 257 + 2147442851 = 2147443108
  • 281 + 2147442827 = 2147443108
  • 311 + 2147442797 = 2147443108
  • 431 + 2147442677 = 2147443108
  • 479 + 2147442629 = 2147443108
  • 641 + 2147442467 = 2147443108

Showing the first eight; more decompositions exist.
