Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81652, here are decompositions:

3 + 81649 = 81652
5 + 81647 = 81652
23 + 81629 = 81652
41 + 81611 = 81652
83 + 81569 = 81652
89 + 81563 = 81652
101 + 81551 = 81652
251 + 81401 = 81652

Showing the first eight; more decompositions exist.
