Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615244, here are decompositions:

7 + 8615237 = 8615244
13 + 8615231 = 8615244
47 + 8615197 = 8615244
67 + 8615177 = 8615244
83 + 8615161 = 8615244
107 + 8615137 = 8615244
181 + 8615063 = 8615244
193 + 8615051 = 8615244

Showing the first eight; more decompositions exist.
