Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003966, here are decompositions:

3 + 1003963 = 1003966
23 + 1003943 = 1003966
53 + 1003913 = 1003966
59 + 1003907 = 1003966
149 + 1003817 = 1003966
179 + 1003787 = 1003966
233 + 1003733 = 1003966
347 + 1003619 = 1003966

Showing the first eight; more decompositions exist.
