Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487156, here are decompositions:

  • 43 + 2147487113 = 2147487156
  • 79 + 2147487077 = 2147487156
  • 97 + 2147487059 = 2147487156
  • 107 + 2147487049 = 2147487156
  • 127 + 2147487029 = 2147487156
  • 229 + 2147486927 = 2147487156
  • 277 + 2147486879 = 2147487156
  • 307 + 2147486849 = 2147487156

Showing the first eight; more decompositions exist.
