Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562346, here are decompositions:

17 + 31562329 = 31562346
47 + 31562299 = 31562346
73 + 31562273 = 31562346
83 + 31562263 = 31562346
89 + 31562257 = 31562346
103 + 31562243 = 31562346
227 + 31562119 = 31562346
229 + 31562117 = 31562346

Showing the first eight; more decompositions exist.
