Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498542, here are decompositions:

  • 23 + 2147498519 = 2147498542
  • 41 + 2147498501 = 2147498542
  • 71 + 2147498471 = 2147498542
  • 149 + 2147498393 = 2147498542
  • 179 + 2147498363 = 2147498542
  • 263 + 2147498279 = 2147498542
  • 353 + 2147498189 = 2147498542
  • 401 + 2147498141 = 2147498542

Showing the first eight; more decompositions exist.
