Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161694, here are decompositions:

11 + 161683 = 161694
53 + 161641 = 161694
67 + 161627 = 161694
83 + 161611 = 161694
103 + 161591 = 161694
131 + 161563 = 161694
151 + 161543 = 161694
163 + 161531 = 161694

Showing the first eight; more decompositions exist.
