Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561980, here are decompositions:

7 + 561973 = 561980
19 + 561961 = 561980
37 + 561943 = 561980
73 + 561907 = 561980
151 + 561829 = 561980
193 + 561787 = 561980
277 + 561703 = 561980
313 + 561667 = 561980

Showing the first eight; more decompositions exist.
