Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730380, here are decompositions:

3 + 8730377 = 8730380
31 + 8730349 = 8730380
37 + 8730343 = 8730380
73 + 8730307 = 8730380
97 + 8730283 = 8730380
151 + 8730229 = 8730380
199 + 8730181 = 8730380
223 + 8730157 = 8730380

Showing the first eight; more decompositions exist.
