Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668472, here are decompositions:

13 + 8668459 = 8668472
103 + 8668369 = 8668472
193 + 8668279 = 8668472
199 + 8668273 = 8668472
271 + 8668201 = 8668472
331 + 8668141 = 8668472
409 + 8668063 = 8668472
499 + 8667973 = 8668472

Showing the first eight; more decompositions exist.
