Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562262, here are decompositions:

5 + 31562257 = 31562262
19 + 31562243 = 31562262
31 + 31562231 = 31562262
163 + 31562099 = 31562262
229 + 31562033 = 31562262
239 + 31562023 = 31562262
269 + 31561993 = 31562262
293 + 31561969 = 31562262

Showing the first eight; more decompositions exist.
