Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615228, here are decompositions:

31 + 8615197 = 8615228
67 + 8615161 = 8615228
79 + 8615149 = 8615228
211 + 8615017 = 8615228
241 + 8614987 = 8615228
277 + 8614951 = 8615228
379 + 8614849 = 8615228
397 + 8614831 = 8615228

Showing the first eight; more decompositions exist.
