Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510990, here are decompositions:

47 + 510943 = 510990
59 + 510931 = 510990
71 + 510919 = 510990
83 + 510907 = 510990
101 + 510889 = 510990
163 + 510827 = 510990
167 + 510823 = 510990
173 + 510817 = 510990

Showing the first eight; more decompositions exist.
