Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561746, here are decompositions:

13 + 561733 = 561746
43 + 561703 = 561746
79 + 561667 = 561746
139 + 561607 = 561746
193 + 561553 = 561746
307 + 561439 = 561746
337 + 561409 = 561746
373 + 561373 = 561746

Showing the first eight; more decompositions exist.
