Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003686, here are decompositions:

7 + 1003679 = 1003686
59 + 1003627 = 1003686
67 + 1003619 = 1003686
97 + 1003589 = 1003686
137 + 1003549 = 1003686
179 + 1003507 = 1003686
223 + 1003463 = 1003686
269 + 1003417 = 1003686

Showing the first eight; more decompositions exist.
