Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556980, here are decompositions:

13 + 556967 = 556980
23 + 556957 = 556980
37 + 556943 = 556980
41 + 556939 = 556980
89 + 556891 = 556980
97 + 556883 = 556980
113 + 556867 = 556980
131 + 556849 = 556980

Showing the first eight; more decompositions exist.
