Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562394, here are decompositions:

5 + 31562389 = 31562394
37 + 31562357 = 31562394
47 + 31562347 = 31562394
103 + 31562291 = 31562394
113 + 31562281 = 31562394
131 + 31562263 = 31562394
137 + 31562257 = 31562394
151 + 31562243 = 31562394

Showing the first eight; more decompositions exist.
