Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81462, here are decompositions:

5 + 81457 = 81462
23 + 81439 = 81462
41 + 81421 = 81462
53 + 81409 = 81462
61 + 81401 = 81462
89 + 81373 = 81462
103 + 81359 = 81462
109 + 81353 = 81462

Showing the first eight; more decompositions exist.
