Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561794, here are decompositions:

7 + 561787 = 561794
61 + 561733 = 561794
127 + 561667 = 561794
241 + 561553 = 561794
421 + 561373 = 561794
487 + 561307 = 561794
613 + 561181 = 561794
691 + 561103 = 561794

Showing the first eight; more decompositions exist.
