Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162490, here are decompositions:

17 + 162473 = 162490
71 + 162419 = 162490
101 + 162389 = 162490
131 + 162359 = 162490
197 + 162293 = 162490
227 + 162263 = 162490
233 + 162257 = 162490
239 + 162251 = 162490

Showing the first eight; more decompositions exist.
