Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534022, here are decompositions:

43 + 31533979 = 31534022
73 + 31533949 = 31534022
103 + 31533919 = 31534022
151 + 31533871 = 31534022
193 + 31533829 = 31534022
199 + 31533823 = 31534022
409 + 31533613 = 31534022
523 + 31533499 = 31534022

Showing the first eight; more decompositions exist.
