Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562264, here are decompositions:

3 + 31562261 = 31562264
7 + 31562257 = 31562264
127 + 31562137 = 31562264
157 + 31562107 = 31562264
211 + 31562053 = 31562264
241 + 31562023 = 31562264
271 + 31561993 = 31562264
337 + 31561927 = 31562264

Showing the first eight; more decompositions exist.
