Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169250, here are decompositions:

7 + 169243 = 169250
31 + 169219 = 169250
73 + 169177 = 169250
139 + 169111 = 169250
157 + 169093 = 169250
181 + 169069 = 169250
241 + 169009 = 169250
307 + 168943 = 169250

Showing the first eight; more decompositions exist.
