Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5656, here are decompositions:

3 + 5653 = 5656
5 + 5651 = 5656
17 + 5639 = 5656
83 + 5573 = 5656
137 + 5519 = 5656
149 + 5507 = 5656
173 + 5483 = 5656
179 + 5477 = 5656

Showing the first eight; more decompositions exist.
