Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81654, here are decompositions:

5 + 81649 = 81654
7 + 81647 = 81654
17 + 81637 = 81654
43 + 81611 = 81654
101 + 81553 = 81654
103 + 81551 = 81654
107 + 81547 = 81654
127 + 81527 = 81654

Showing the first eight; more decompositions exist.
