Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65656, here are decompositions:

5 + 65651 = 65656
23 + 65633 = 65656
47 + 65609 = 65656
113 + 65543 = 65656
137 + 65519 = 65656
233 + 65423 = 65656
263 + 65393 = 65656
347 + 65309 = 65656

Showing the first eight; more decompositions exist.
