Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506990, here are decompositions:

7 + 506983 = 506990
61 + 506929 = 506990
79 + 506911 = 506990
97 + 506893 = 506990
103 + 506887 = 506990
181 + 506809 = 506990
193 + 506797 = 506990
199 + 506791 = 506990

Showing the first eight; more decompositions exist.
