Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429308, here are decompositions:

  • 71 + 2147429237 = 2147429308
  • 251 + 2147429057 = 2147429308
  • 317 + 2147428991 = 2147429308
  • 359 + 2147428949 = 2147429308
  • 569 + 2147428739 = 2147429308
  • 599 + 2147428709 = 2147429308
  • 887 + 2147428421 = 2147429308
  • 1031 + 2147428277 = 2147429308

Showing the first eight; more decompositions exist.
