Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565726, here are decompositions:

3 + 565723 = 565726
59 + 565667 = 565726
89 + 565637 = 565726
113 + 565613 = 565726
137 + 565589 = 565726
167 + 565559 = 565726
173 + 565553 = 565726
257 + 565469 = 565726

Showing the first eight; more decompositions exist.
