Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668338, here are decompositions:

37 + 8668301 = 8668338
59 + 8668279 = 8668338
71 + 8668267 = 8668338
131 + 8668207 = 8668338
137 + 8668201 = 8668338
181 + 8668157 = 8668338
197 + 8668141 = 8668338
227 + 8668111 = 8668338

Showing the first eight; more decompositions exist.
