Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663538, here are decompositions:

17 + 8663521 = 8663538
19 + 8663519 = 8663538
29 + 8663509 = 8663538
31 + 8663507 = 8663538
41 + 8663497 = 8663538
67 + 8663471 = 8663538
71 + 8663467 = 8663538
97 + 8663441 = 8663538

Showing the first eight; more decompositions exist.
