Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657442, here are decompositions:

11 + 8657431 = 8657442
19 + 8657423 = 8657442
61 + 8657381 = 8657442
109 + 8657333 = 8657442
151 + 8657291 = 8657442
193 + 8657249 = 8657442
281 + 8657161 = 8657442
331 + 8657111 = 8657442

Showing the first eight; more decompositions exist.
