Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5646, here are decompositions:

5 + 5641 = 5646
7 + 5639 = 5646
23 + 5623 = 5646
73 + 5573 = 5646
83 + 5563 = 5646
89 + 5557 = 5646
127 + 5519 = 5646
139 + 5507 = 5646

Showing the first eight; more decompositions exist.
