Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562358, here are decompositions:

11 + 31562347 = 31562358
29 + 31562329 = 31562358
59 + 31562299 = 31562358
67 + 31562291 = 31562358
97 + 31562261 = 31562358
101 + 31562257 = 31562358
127 + 31562231 = 31562358
239 + 31562119 = 31562358

Showing the first eight; more decompositions exist.
