Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501478, here are decompositions:

  • 41 + 2147501437 = 2147501478
  • 47 + 2147501431 = 2147501478
  • 229 + 2147501249 = 2147501478
  • 257 + 2147501221 = 2147501478
  • 347 + 2147501131 = 2147501478
  • 349 + 2147501129 = 2147501478
  • 389 + 2147501089 = 2147501478
  • 401 + 2147501077 = 2147501478

Showing the first eight; more decompositions exist.
