Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123654, here are decompositions:

17 + 123637 = 123654
23 + 123631 = 123654
53 + 123601 = 123654
61 + 123593 = 123654
71 + 123583 = 123654
73 + 123581 = 123654
101 + 123553 = 123654
103 + 123551 = 123654

Showing the first eight; more decompositions exist.
