Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81622, here are decompositions:

3 + 81619 = 81622
11 + 81611 = 81622
53 + 81569 = 81622
59 + 81563 = 81622
71 + 81551 = 81622
89 + 81533 = 81622
113 + 81509 = 81622
251 + 81371 = 81622

Showing the first eight; more decompositions exist.
