Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661506, here are decompositions:

19 + 8661487 = 8661506
37 + 8661469 = 8661506
67 + 8661439 = 8661506
79 + 8661427 = 8661506
283 + 8661223 = 8661506
313 + 8661193 = 8661506
457 + 8661049 = 8661506
463 + 8661043 = 8661506

Showing the first eight; more decompositions exist.
