Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562266, here are decompositions:

3 + 31562263 = 31562266
5 + 31562261 = 31562266
23 + 31562243 = 31562266
53 + 31562213 = 31562266
149 + 31562117 = 31562266
167 + 31562099 = 31562266
173 + 31562093 = 31562266
233 + 31562033 = 31562266

Showing the first eight; more decompositions exist.
