Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102654, here are decompositions:

7 + 102647 = 102654
11 + 102643 = 102654
43 + 102611 = 102654
47 + 102607 = 102654
61 + 102593 = 102654
67 + 102587 = 102654
103 + 102551 = 102654
107 + 102547 = 102654

Showing the first eight; more decompositions exist.
