Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498442, here are decompositions:

  • 29 + 2147498413 = 2147498442
  • 43 + 2147498399 = 2147498442
  • 79 + 2147498363 = 2147498442
  • 101 + 2147498341 = 2147498442
  • 109 + 2147498333 = 2147498442
  • 163 + 2147498279 = 2147498442
  • 233 + 2147498209 = 2147498442
  • 263 + 2147498179 = 2147498442

Showing the first eight; more decompositions exist.
