Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161594, here are decompositions:

3 + 161591 = 161594
31 + 161563 = 161594
67 + 161527 = 161594
73 + 161521 = 161594
271 + 161323 = 161594
313 + 161281 = 161594
331 + 161263 = 161594
373 + 161221 = 161594

Showing the first eight; more decompositions exist.
