Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548990, here are decompositions:

7 + 31548983 = 31548990
29 + 31548961 = 31548990
37 + 31548953 = 31548990
167 + 31548823 = 31548990
173 + 31548817 = 31548990
223 + 31548767 = 31548990
227 + 31548763 = 31548990
233 + 31548757 = 31548990

Showing the first eight; more decompositions exist.
