Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632688, here are decompositions:

67 + 8632621 = 8632688
79 + 8632609 = 8632688
109 + 8632579 = 8632688
157 + 8632531 = 8632688
199 + 8632489 = 8632688
277 + 8632411 = 8632688
307 + 8632381 = 8632688
331 + 8632357 = 8632688

Showing the first eight; more decompositions exist.
