Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615774, here are decompositions:

3 + 8615771 = 8615774
7 + 8615767 = 8615774
67 + 8615707 = 8615774
151 + 8615623 = 8615774
283 + 8615491 = 8615774
313 + 8615461 = 8615774
397 + 8615377 = 8615774
487 + 8615287 = 8615774

Showing the first eight; more decompositions exist.
