Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81672, here are decompositions:

5 + 81667 = 81672
23 + 81649 = 81672
43 + 81629 = 81672
53 + 81619 = 81672
61 + 81611 = 81672
103 + 81569 = 81672
109 + 81563 = 81672
113 + 81559 = 81672

Showing the first eight; more decompositions exist.
