Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498380, here are decompositions:

  • 17 + 2147498363 = 2147498380
  • 47 + 2147498333 = 2147498380
  • 101 + 2147498279 = 2147498380
  • 191 + 2147498189 = 2147498380
  • 233 + 2147498147 = 2147498380
  • 239 + 2147498141 = 2147498380
  • 263 + 2147498117 = 2147498380
  • 347 + 2147498033 = 2147498380

Showing the first eight; more decompositions exist.
