Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562286, here are decompositions:

5 + 31562281 = 31562286
13 + 31562273 = 31562286
23 + 31562263 = 31562286
29 + 31562257 = 31562286
43 + 31562243 = 31562286
73 + 31562213 = 31562286
149 + 31562137 = 31562286
167 + 31562119 = 31562286

Showing the first eight; more decompositions exist.
