Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662658, here are decompositions:

61 + 8662597 = 8662658
79 + 8662579 = 8662658
127 + 8662531 = 8662658
211 + 8662447 = 8662658
331 + 8662327 = 8662658
379 + 8662279 = 8662658
409 + 8662249 = 8662658
439 + 8662219 = 8662658

Showing the first eight; more decompositions exist.
