Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562260, here are decompositions:

3 + 31562257 = 31562260
17 + 31562243 = 31562260
29 + 31562231 = 31562260
47 + 31562213 = 31562260
167 + 31562093 = 31562260
227 + 31562033 = 31562260
251 + 31562009 = 31562260
293 + 31561967 = 31562260

Showing the first eight; more decompositions exist.
