Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 535872, here are decompositions:

11 + 535861 = 535872
13 + 535859 = 535872
23 + 535849 = 535872
61 + 535811 = 535872
79 + 535793 = 535872
89 + 535783 = 535872
101 + 535771 = 535872
131 + 535741 = 535872

Showing the first eight; more decompositions exist.
