Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64272, here are decompositions:

41 + 64231 = 64272
83 + 64189 = 64272
101 + 64171 = 64272
149 + 64123 = 64272
163 + 64109 = 64272
181 + 64091 = 64272
191 + 64081 = 64272
239 + 64033 = 64272

Showing the first eight; more decompositions exist.
