Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161682, here are decompositions:

23 + 161659 = 161682
41 + 161641 = 161682
43 + 161639 = 161682
71 + 161611 = 161682
83 + 161599 = 161682
109 + 161573 = 161682
113 + 161569 = 161682
139 + 161543 = 161682

Showing the first eight; more decompositions exist.
