Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659442, here are decompositions:

19 + 8659423 = 8659442
61 + 8659381 = 8659442
79 + 8659363 = 8659442
163 + 8659279 = 8659442
199 + 8659243 = 8659442
223 + 8659219 = 8659442
433 + 8659009 = 8659442
499 + 8658943 = 8659442

Showing the first eight; more decompositions exist.
