Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718422, here are decompositions:

3 + 8718419 = 8718422
73 + 8718349 = 8718422
79 + 8718343 = 8718422
109 + 8718313 = 8718422
151 + 8718271 = 8718422
313 + 8718109 = 8718422
331 + 8718091 = 8718422
379 + 8718043 = 8718422

Showing the first eight; more decompositions exist.
