Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615288, here are decompositions:

127 + 8615161 = 8615288
139 + 8615149 = 8615288
151 + 8615137 = 8615288
271 + 8615017 = 8615288
337 + 8614951 = 8615288
349 + 8614939 = 8615288
421 + 8614867 = 8615288
439 + 8614849 = 8615288

Showing the first eight; more decompositions exist.
