Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169238, here are decompositions:

19 + 169219 = 169238
61 + 169177 = 169238
79 + 169159 = 169238
109 + 169129 = 169238
127 + 169111 = 169238
229 + 169009 = 169238
337 + 168901 = 169238
457 + 168781 = 169238

Showing the first eight; more decompositions exist.
