Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498620, here are decompositions:

  • 101 + 2147498519 = 2147498620
  • 149 + 2147498471 = 2147498620
  • 227 + 2147498393 = 2147498620
  • 233 + 2147498387 = 2147498620
  • 257 + 2147498363 = 2147498620
  • 431 + 2147498189 = 2147498620
  • 479 + 2147498141 = 2147498620
  • 503 + 2147498117 = 2147498620

Showing the first eight; more decompositions exist.
