Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522044, here are decompositions:

23 + 31522021 = 31522044
31 + 31522013 = 31522044
53 + 31521991 = 31522044
67 + 31521977 = 31522044
157 + 31521887 = 31522044
181 + 31521863 = 31522044
193 + 31521851 = 31522044
251 + 31521793 = 31522044

Showing the first eight; more decompositions exist.
