Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81762, here are decompositions:

13 + 81749 = 81762
59 + 81703 = 81762
61 + 81701 = 81762
73 + 81689 = 81762
113 + 81649 = 81762
151 + 81611 = 81762
193 + 81569 = 81762
199 + 81563 = 81762

Showing the first eight; more decompositions exist.
