Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532872, here are decompositions:

5 + 532867 = 532872
19 + 532853 = 532872
23 + 532849 = 532872
61 + 532811 = 532872
71 + 532801 = 532872
83 + 532789 = 532872
89 + 532783 = 532872
101 + 532771 = 532872

Showing the first eight; more decompositions exist.
