Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615222, here are decompositions:

3 + 8615219 = 8615222
61 + 8615161 = 8615222
73 + 8615149 = 8615222
139 + 8615083 = 8615222
271 + 8614951 = 8615222
283 + 8614939 = 8615222
349 + 8614873 = 8615222
373 + 8614849 = 8615222

Showing the first eight; more decompositions exist.
