Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979990, here are decompositions:

3 + 979987 = 979990
41 + 979949 = 979990
71 + 979919 = 979990
83 + 979907 = 979990
101 + 979889 = 979990
107 + 979883 = 979990
233 + 979757 = 979990
281 + 979709 = 979990

Showing the first eight; more decompositions exist.
