Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555990, here are decompositions:

23 + 555967 = 555990
37 + 555953 = 555990
59 + 555931 = 555990
137 + 555853 = 555990
163 + 555827 = 555990
167 + 555823 = 555990
223 + 555767 = 555990
229 + 555761 = 555990

Showing the first eight; more decompositions exist.
