Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000990, here are decompositions:

17 + 1000973 = 1000990
59 + 1000931 = 1000990
71 + 1000919 = 1000990
83 + 1000907 = 1000990
101 + 1000889 = 1000990
131 + 1000859 = 1000990
197 + 1000793 = 1000990
227 + 1000763 = 1000990

Showing the first eight; more decompositions exist.
