Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566690, here are decompositions:

13 + 566677 = 566690
31 + 566659 = 566690
37 + 566653 = 566690
73 + 566617 = 566690
127 + 566563 = 566690
139 + 566551 = 566690
151 + 566539 = 566690
277 + 566413 = 566690

Showing the first eight; more decompositions exist.
