Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003990, here are decompositions:

47 + 1003943 = 1003990
59 + 1003931 = 1003990
83 + 1003907 = 1003990
101 + 1003889 = 1003990
149 + 1003841 = 1003990
173 + 1003817 = 1003990
227 + 1003763 = 1003990
233 + 1003757 = 1003990

Showing the first eight; more decompositions exist.
