Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615140, here are decompositions:

3 + 8615137 = 8615140
41 + 8615099 = 8615140
89 + 8615051 = 8615140
167 + 8614973 = 8615140
173 + 8614967 = 8615140
227 + 8614913 = 8615140
239 + 8614901 = 8615140
251 + 8614889 = 8615140

Showing the first eight; more decompositions exist.
