Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161524, here are decompositions:

3 + 161521 = 161524
17 + 161507 = 161524
53 + 161471 = 161524
71 + 161453 = 161524
113 + 161411 = 161524
137 + 161387 = 161524
191 + 161333 = 161524
257 + 161267 = 161524

Showing the first eight; more decompositions exist.
