Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561366, here are decompositions:

7 + 561359 = 561366
19 + 561347 = 561366
23 + 561343 = 561366
53 + 561313 = 561366
59 + 561307 = 561366
89 + 561277 = 561366
137 + 561229 = 561366
167 + 561199 = 561366

Showing the first eight; more decompositions exist.
