Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742330, here are decompositions:

13 + 8742317 = 8742330
17 + 8742313 = 8742330
67 + 8742263 = 8742330
71 + 8742259 = 8742330
137 + 8742193 = 8742330
173 + 8742157 = 8742330
197 + 8742133 = 8742330
227 + 8742103 = 8742330

Showing the first eight; more decompositions exist.
