Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648646, here are decompositions:

89 + 8648557 = 8648646
103 + 8648543 = 8648646
109 + 8648537 = 8648646
113 + 8648533 = 8648646
199 + 8648447 = 8648646
233 + 8648413 = 8648646
257 + 8648389 = 8648646
277 + 8648369 = 8648646

Showing the first eight; more decompositions exist.
