Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668628, here are decompositions:

19 + 8668609 = 8668628
79 + 8668549 = 8668628
109 + 8668519 = 8668628
127 + 8668501 = 8668628
139 + 8668489 = 8668628
271 + 8668357 = 8668628
349 + 8668279 = 8668628
421 + 8668207 = 8668628

Showing the first eight; more decompositions exist.
