Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659418, here are decompositions:

37 + 8659381 = 8659418
67 + 8659351 = 8659418
109 + 8659309 = 8659418
139 + 8659279 = 8659418
199 + 8659219 = 8659418
211 + 8659207 = 8659418
367 + 8659051 = 8659418
409 + 8659009 = 8659418

Showing the first eight; more decompositions exist.
