Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561790, here are decompositions:

3 + 561787 = 561790
23 + 561767 = 561790
29 + 561761 = 561790
191 + 561599 = 561790
239 + 561551 = 561790
269 + 561521 = 561790
401 + 561389 = 561790
431 + 561359 = 561790

Showing the first eight; more decompositions exist.
