Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615164, here are decompositions:

3 + 8615161 = 8615164
101 + 8615063 = 8615164
113 + 8615051 = 8615164
191 + 8614973 = 8615164
197 + 8614967 = 8615164
251 + 8614913 = 8615164
263 + 8614901 = 8615164
281 + 8614883 = 8615164

Showing the first eight; more decompositions exist.
