Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550872, here are decompositions:

11 + 550861 = 550872
13 + 550859 = 550872
29 + 550843 = 550872
31 + 550841 = 550872
41 + 550831 = 550872
59 + 550813 = 550872
61 + 550811 = 550872
71 + 550801 = 550872

Showing the first eight; more decompositions exist.
