Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498902, here are decompositions:

  • 71 + 2147498831 = 2147498902
  • 89 + 2147498813 = 2147498902
  • 173 + 2147498729 = 2147498902
  • 179 + 2147498723 = 2147498902
  • 359 + 2147498543 = 2147498902
  • 383 + 2147498519 = 2147498902
  • 401 + 2147498501 = 2147498902
  • 431 + 2147498471 = 2147498902

Showing the first eight; more decompositions exist.
