Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501146, here are decompositions:

  • 3 + 2147501143 = 2147501146
  • 17 + 2147501129 = 2147501146
  • 137 + 2147501009 = 2147501146
  • 239 + 2147500907 = 2147501146
  • 257 + 2147500889 = 2147501146
  • 383 + 2147500763 = 2147501146
  • 449 + 2147500697 = 2147501146
  • 587 + 2147500559 = 2147501146

Showing the first eight; more decompositions exist.
