Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81962, here are decompositions:

19 + 81943 = 81962
31 + 81931 = 81962
43 + 81919 = 81962
61 + 81901 = 81962
79 + 81883 = 81962
109 + 81853 = 81962
163 + 81799 = 81962
193 + 81769 = 81962

Showing the first eight; more decompositions exist.
