Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161456, here are decompositions:

3 + 161453 = 161456
79 + 161377 = 161456
193 + 161263 = 161456
223 + 161233 = 161456
307 + 161149 = 161456
397 + 161059 = 161456
409 + 161047 = 161456
439 + 161017 = 161456

Showing the first eight; more decompositions exist.
