Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15644, here are decompositions:

3 + 15641 = 15644
37 + 15607 = 15644
43 + 15601 = 15644
61 + 15583 = 15644
103 + 15541 = 15644
151 + 15493 = 15644
193 + 15451 = 15644
271 + 15373 = 15644

Showing the first eight; more decompositions exist.
