Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615380, here are decompositions:

3 + 8615377 = 8615380
47 + 8615333 = 8615380
101 + 8615279 = 8615380
107 + 8615273 = 8615380
113 + 8615267 = 8615380
149 + 8615231 = 8615380
281 + 8615099 = 8615380
317 + 8615063 = 8615380

Showing the first eight; more decompositions exist.
