Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155682, here are decompositions:

11 + 155671 = 155682
19 + 155663 = 155682
29 + 155653 = 155682
61 + 155621 = 155682
73 + 155609 = 155682
83 + 155599 = 155682
89 + 155593 = 155682
101 + 155581 = 155682

Showing the first eight; more decompositions exist.
