Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161488, here are decompositions:

17 + 161471 = 161488
29 + 161459 = 161488
101 + 161387 = 161488
149 + 161339 = 161488
179 + 161309 = 161488
251 + 161237 = 161488
347 + 161141 = 161488
401 + 161087 = 161488

Showing the first eight; more decompositions exist.
