Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161498, here are decompositions:

37 + 161461 = 161498
157 + 161341 = 161498
277 + 161221 = 161498
331 + 161167 = 161498
349 + 161149 = 161498
439 + 161059 = 161498
619 + 160879 = 161498
691 + 160807 = 161498

Showing the first eight; more decompositions exist.
