Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562276, here are decompositions:

3 + 31562273 = 31562276
13 + 31562263 = 31562276
19 + 31562257 = 31562276
139 + 31562137 = 31562276
157 + 31562119 = 31562276
223 + 31562053 = 31562276
283 + 31561993 = 31562276
307 + 31561969 = 31562276

Showing the first eight; more decompositions exist.
