Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556020, here are decompositions:

13 + 556007 = 556020
53 + 555967 = 556020
67 + 555953 = 556020
79 + 555941 = 556020
89 + 555931 = 556020
149 + 555871 = 556020
163 + 555857 = 556020
167 + 555853 = 556020

Showing the first eight; more decompositions exist.
