Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65564, here are decompositions:

7 + 65557 = 65564
13 + 65551 = 65564
43 + 65521 = 65564
67 + 65497 = 65564
127 + 65437 = 65564
151 + 65413 = 65564
157 + 65407 = 65564
193 + 65371 = 65564

Showing the first eight; more decompositions exist.
