Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663668, here are decompositions:

47 + 8663621 = 8663668
59 + 8663609 = 8663668
89 + 8663579 = 8663668
131 + 8663537 = 8663668
149 + 8663519 = 8663668
197 + 8663471 = 8663668
227 + 8663441 = 8663668
311 + 8663357 = 8663668

Showing the first eight; more decompositions exist.
