Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030990, here are decompositions:

3 + 1030987 = 1030990
41 + 1030949 = 1030990
71 + 1030919 = 1030990
101 + 1030889 = 1030990
167 + 1030823 = 1030990
173 + 1030817 = 1030990
179 + 1030811 = 1030990
197 + 1030793 = 1030990

Showing the first eight; more decompositions exist.
