Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169490, here are decompositions:

7 + 169483 = 169490
19 + 169471 = 169490
151 + 169339 = 169490
163 + 169327 = 169490
241 + 169249 = 169490
271 + 169219 = 169490
313 + 169177 = 169490
331 + 169159 = 169490

Showing the first eight; more decompositions exist.
