Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615072, here are decompositions:

199 + 8614873 = 8615072
223 + 8614849 = 8615072
241 + 8614831 = 8615072
283 + 8614789 = 8615072
313 + 8614759 = 8615072
379 + 8614693 = 8615072
421 + 8614651 = 8615072
463 + 8614609 = 8615072

Showing the first eight; more decompositions exist.
