Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498454, here are decompositions:

  • 5 + 2147498449 = 2147498454
  • 41 + 2147498413 = 2147498454
  • 61 + 2147498393 = 2147498454
  • 67 + 2147498387 = 2147498454
  • 107 + 2147498347 = 2147498454
  • 113 + 2147498341 = 2147498454
  • 307 + 2147498147 = 2147498454
  • 313 + 2147498141 = 2147498454

Showing the first eight; more decompositions exist.
