Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81634, here are decompositions:

5 + 81629 = 81634
23 + 81611 = 81634
71 + 81563 = 81634
83 + 81551 = 81634
101 + 81533 = 81634
107 + 81527 = 81634
233 + 81401 = 81634
263 + 81371 = 81634

Showing the first eight; more decompositions exist.
