Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003688, here are decompositions:

61 + 1003627 = 1003688
67 + 1003621 = 1003688
79 + 1003609 = 1003688
139 + 1003549 = 1003688
181 + 1003507 = 1003688
271 + 1003417 = 1003688
277 + 1003411 = 1003688
307 + 1003381 = 1003688

Showing the first eight; more decompositions exist.
