Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553866, here are decompositions:

17 + 553849 = 553866
29 + 553837 = 553866
97 + 553769 = 553866
107 + 553759 = 553866
109 + 553757 = 553866
139 + 553727 = 553866
163 + 553703 = 553866
167 + 553699 = 553866

Showing the first eight; more decompositions exist.
