Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576022, here are decompositions:

13 + 31576009 = 31576022
19 + 31576003 = 31576022
31 + 31575991 = 31576022
193 + 31575829 = 31576022
199 + 31575823 = 31576022
223 + 31575799 = 31576022
229 + 31575793 = 31576022
523 + 31575499 = 31576022

Showing the first eight; more decompositions exist.
