Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468918, here are decompositions:

17 + 31468901 = 31468918
191 + 31468727 = 31468918
251 + 31468667 = 31468918
281 + 31468637 = 31468918
347 + 31468571 = 31468918
359 + 31468559 = 31468918
389 + 31468529 = 31468918
401 + 31468517 = 31468918

Showing the first eight; more decompositions exist.
