Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159490, here are decompositions:

17 + 159473 = 159490
53 + 159437 = 159490
59 + 159431 = 159490
83 + 159407 = 159490
101 + 159389 = 159490
179 + 159311 = 159490
197 + 159293 = 159490
257 + 159233 = 159490

Showing the first eight; more decompositions exist.
