Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615236, here are decompositions:

5 + 8615231 = 8615236
17 + 8615219 = 8615236
59 + 8615177 = 8615236
137 + 8615099 = 8615236
173 + 8615063 = 8615236
257 + 8614979 = 8615236
263 + 8614973 = 8615236
269 + 8614967 = 8615236

Showing the first eight; more decompositions exist.
