Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663638, here are decompositions:

17 + 8663621 = 8663638
29 + 8663609 = 8663638
59 + 8663579 = 8663638
101 + 8663537 = 8663638
131 + 8663507 = 8663638
167 + 8663471 = 8663638
197 + 8663441 = 8663638
281 + 8663357 = 8663638

Showing the first eight; more decompositions exist.
