Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15654, here are decompositions:

5 + 15649 = 15654
7 + 15647 = 15654
11 + 15643 = 15654
13 + 15641 = 15654
47 + 15607 = 15654
53 + 15601 = 15654
71 + 15583 = 15654
73 + 15581 = 15654

Showing the first eight; more decompositions exist.
