Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550990, here are decompositions:

17 + 550973 = 550990
29 + 550961 = 550990
53 + 550937 = 550990
131 + 550859 = 550990
149 + 550841 = 550990
179 + 550811 = 550990
227 + 550763 = 550990
233 + 550757 = 550990

Showing the first eight; more decompositions exist.
