Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429136, here are decompositions:

  • 5 + 2147429131 = 2147429136
  • 79 + 2147429057 = 2147429136
  • 89 + 2147429047 = 2147429136
  • 113 + 2147429023 = 2147429136
  • 137 + 2147428999 = 2147429136
  • 179 + 2147428957 = 2147429136
  • 313 + 2147428823 = 2147429136
  • 317 + 2147428819 = 2147429136

Showing the first eight; more decompositions exist.
