Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153490, here are decompositions:

3 + 153487 = 153490
41 + 153449 = 153490
47 + 153443 = 153490
53 + 153437 = 153490
83 + 153407 = 153490
131 + 153359 = 153490
137 + 153353 = 153490
353 + 153137 = 153490

Showing the first eight; more decompositions exist.
