Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490178, here are decompositions:

19 + 490159 = 490178
61 + 490117 = 490178
67 + 490111 = 490178
277 + 489901 = 490178
307 + 489871 = 490178
331 + 489847 = 490178
379 + 489799 = 490178
487 + 489691 = 490178

Showing the first eight; more decompositions exist.
