Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615012, here are decompositions:

61 + 8614951 = 8615012
73 + 8614939 = 8615012
139 + 8614873 = 8615012
163 + 8614849 = 8615012
181 + 8614831 = 8615012
223 + 8614789 = 8615012
229 + 8614783 = 8615012
283 + 8614729 = 8615012

Showing the first eight; more decompositions exist.
