Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452222, here are decompositions:

13 + 31452209 = 31452222
19 + 31452203 = 31452222
23 + 31452199 = 31452222
41 + 31452181 = 31452222
101 + 31452121 = 31452222
181 + 31452041 = 31452222
223 + 31451999 = 31452222
229 + 31451993 = 31452222

Showing the first eight; more decompositions exist.
