Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615172, here are decompositions:

11 + 8615161 = 8615172
23 + 8615149 = 8615172
73 + 8615099 = 8615172
89 + 8615083 = 8615172
109 + 8615063 = 8615172
193 + 8614979 = 8615172
199 + 8614973 = 8615172
233 + 8614939 = 8615172

Showing the first eight; more decompositions exist.
