Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663554, here are decompositions:

17 + 8663537 = 8663554
47 + 8663507 = 8663554
83 + 8663471 = 8663554
113 + 8663441 = 8663554
197 + 8663357 = 8663554
281 + 8663273 = 8663554
293 + 8663261 = 8663554
401 + 8663153 = 8663554

Showing the first eight; more decompositions exist.
