Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487186, here are decompositions:

  • 17 + 2147487169 = 2147487186
  • 29 + 2147487157 = 2147487186
  • 73 + 2147487113 = 2147487186
  • 109 + 2147487077 = 2147487186
  • 127 + 2147487059 = 2147487186
  • 137 + 2147487049 = 2147487186
  • 157 + 2147487029 = 2147487186
  • 277 + 2147486909 = 2147487186

Showing the first eight; more decompositions exist.
