Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556972, here are decompositions:

5 + 556967 = 556972
29 + 556943 = 556972
41 + 556931 = 556972
89 + 556883 = 556972
113 + 556859 = 556972
131 + 556841 = 556972
149 + 556823 = 556972
173 + 556799 = 556972

Showing the first eight; more decompositions exist.
