Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615210, here are decompositions:

13 + 8615197 = 8615210
61 + 8615149 = 8615210
73 + 8615137 = 8615210
127 + 8615083 = 8615210
193 + 8615017 = 8615210
223 + 8614987 = 8615210
271 + 8614939 = 8615210
337 + 8614873 = 8615210

Showing the first eight; more decompositions exist.
