Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615284, here are decompositions:

5 + 8615279 = 8615284
11 + 8615273 = 8615284
17 + 8615267 = 8615284
23 + 8615261 = 8615284
47 + 8615237 = 8615284
53 + 8615231 = 8615284
107 + 8615177 = 8615284
233 + 8615051 = 8615284

Showing the first eight; more decompositions exist.
