Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532220, here are decompositions:

37 + 532183 = 532220
61 + 532159 = 532220
67 + 532153 = 532220
79 + 532141 = 532220
127 + 532093 = 532220
151 + 532069 = 532220
193 + 532027 = 532220
211 + 532009 = 532220

Showing the first eight; more decompositions exist.
