Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488990, here are decompositions:

31 + 488959 = 488990
43 + 488947 = 488990
97 + 488893 = 488990
157 + 488833 = 488990
163 + 488827 = 488990
193 + 488797 = 488990
199 + 488791 = 488990
211 + 488779 = 488990

Showing the first eight; more decompositions exist.
