Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556990, here are decompositions:

3 + 556987 = 556990
23 + 556967 = 556990
47 + 556943 = 556990
59 + 556931 = 556990
107 + 556883 = 556990
131 + 556859 = 556990
149 + 556841 = 556990
167 + 556823 = 556990

Showing the first eight; more decompositions exist.
