Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663278, here are decompositions:

5 + 8663273 = 8663278
17 + 8663261 = 8663278
179 + 8663099 = 8663278
389 + 8662889 = 8663278
419 + 8662859 = 8663278
467 + 8662811 = 8663278
479 + 8662799 = 8663278
509 + 8662769 = 8663278

Showing the first eight; more decompositions exist.
