Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498280, here are decompositions:

  • 71 + 2147498209 = 2147498280
  • 101 + 2147498179 = 2147498280
  • 139 + 2147498141 = 2147498280
  • 163 + 2147498117 = 2147498280
  • 331 + 2147497949 = 2147498280
  • 337 + 2147497943 = 2147498280
  • 359 + 2147497921 = 2147498280
  • 373 + 2147497907 = 2147498280

Showing the first eight; more decompositions exist.
