Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659628, here are decompositions:

97 + 8659531 = 8659628
127 + 8659501 = 8659628
157 + 8659471 = 8659628
277 + 8659351 = 8659628
349 + 8659279 = 8659628
409 + 8659219 = 8659628
421 + 8659207 = 8659628
577 + 8659051 = 8659628

Showing the first eight; more decompositions exist.
