Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15672, here are decompositions:

5 + 15667 = 15672
11 + 15661 = 15672
23 + 15649 = 15672
29 + 15643 = 15672
31 + 15641 = 15672
43 + 15629 = 15672
53 + 15619 = 15672
71 + 15601 = 15672

Showing the first eight; more decompositions exist.
