Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490990, here are decompositions:

23 + 490967 = 490990
41 + 490949 = 490990
53 + 490937 = 490990
113 + 490877 = 490990
131 + 490859 = 490990
257 + 490733 = 490990
293 + 490697 = 490990
347 + 490643 = 490990

Showing the first eight; more decompositions exist.
