Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718430, here are decompositions:

3 + 8718427 = 8718430
11 + 8718419 = 8718430
23 + 8718407 = 8718430
29 + 8718401 = 8718430
53 + 8718377 = 8718430
179 + 8718251 = 8718430
233 + 8718197 = 8718430
239 + 8718191 = 8718430

Showing the first eight; more decompositions exist.
