Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620264, here are decompositions:

41 + 31620223 = 31620264
61 + 31620203 = 31620264
73 + 31620191 = 31620264
97 + 31620167 = 31620264
113 + 31620151 = 31620264
157 + 31620107 = 31620264
197 + 31620067 = 31620264
227 + 31620037 = 31620264

Showing the first eight; more decompositions exist.
