Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161502, here are decompositions:

31 + 161471 = 161502
41 + 161461 = 161502
43 + 161459 = 161502
139 + 161363 = 161502
163 + 161339 = 161502
179 + 161323 = 161502
193 + 161309 = 161502
199 + 161303 = 161502

Showing the first eight; more decompositions exist.
