Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532170, here are decompositions:

7 + 532163 = 532170
11 + 532159 = 532170
17 + 532153 = 532170
29 + 532141 = 532170
71 + 532099 = 532170
101 + 532069 = 532170
109 + 532061 = 532170
137 + 532033 = 532170

Showing the first eight; more decompositions exist.
