Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161476, here are decompositions:

5 + 161471 = 161476
17 + 161459 = 161476
23 + 161453 = 161476
89 + 161387 = 161476
113 + 161363 = 161476
137 + 161339 = 161476
167 + 161309 = 161476
173 + 161303 = 161476

Showing the first eight; more decompositions exist.
