Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522144, here are decompositions:

41 + 31522103 = 31522144
53 + 31522091 = 31522144
83 + 31522061 = 31522144
131 + 31522013 = 31522144
167 + 31521977 = 31522144
191 + 31521953 = 31522144
257 + 31521887 = 31522144
281 + 31521863 = 31522144

Showing the first eight; more decompositions exist.
