Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562268, here are decompositions:

5 + 31562263 = 31562268
7 + 31562261 = 31562268
11 + 31562257 = 31562268
37 + 31562231 = 31562268
131 + 31562137 = 31562268
149 + 31562119 = 31562268
151 + 31562117 = 31562268
211 + 31562057 = 31562268

Showing the first eight; more decompositions exist.
