Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615256, here are decompositions:

19 + 8615237 = 8615256
37 + 8615219 = 8615256
59 + 8615197 = 8615256
79 + 8615177 = 8615256
107 + 8615149 = 8615256
157 + 8615099 = 8615256
173 + 8615083 = 8615256
193 + 8615063 = 8615256

Showing the first eight; more decompositions exist.
