Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615672, here are decompositions:

19 + 8615653 = 8615672
181 + 8615491 = 8615672
193 + 8615479 = 8615672
199 + 8615473 = 8615672
211 + 8615461 = 8615672
283 + 8615389 = 8615672
349 + 8615323 = 8615672
523 + 8615149 = 8615672

Showing the first eight; more decompositions exist.
