Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562294, here are decompositions:

3 + 31562291 = 31562294
13 + 31562281 = 31562294
31 + 31562263 = 31562294
37 + 31562257 = 31562294
157 + 31562137 = 31562294
241 + 31562053 = 31562294
271 + 31562023 = 31562294
277 + 31562017 = 31562294

Showing the first eight; more decompositions exist.
