Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161464, here are decompositions:

3 + 161461 = 161464
5 + 161459 = 161464
11 + 161453 = 161464
53 + 161411 = 161464
101 + 161363 = 161464
131 + 161333 = 161464
197 + 161267 = 161464
227 + 161237 = 161464

Showing the first eight; more decompositions exist.
