Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490170, here are decompositions:

11 + 490159 = 490170
19 + 490151 = 490170
53 + 490117 = 490170
59 + 490111 = 490170
67 + 490103 = 490170
73 + 490097 = 490170
113 + 490057 = 490170
137 + 490033 = 490170

Showing the first eight; more decompositions exist.
