Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561358, here are decompositions:

11 + 561347 = 561358
107 + 561251 = 561358
167 + 561191 = 561358
197 + 561161 = 561358
257 + 561101 = 561358
311 + 561047 = 561358
389 + 560969 = 561358
419 + 560939 = 561358

Showing the first eight; more decompositions exist.
