Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562366, here are decompositions:

19 + 31562347 = 31562366
37 + 31562329 = 31562366
67 + 31562299 = 31562366
103 + 31562263 = 31562366
109 + 31562257 = 31562366
229 + 31562137 = 31562366
313 + 31562053 = 31562366
349 + 31562017 = 31562366

Showing the first eight; more decompositions exist.
