Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572246, here are decompositions:

5 + 31572241 = 31572246
19 + 31572227 = 31572246
23 + 31572223 = 31572246
89 + 31572157 = 31572246
103 + 31572143 = 31572246
113 + 31572133 = 31572246
163 + 31572083 = 31572246
197 + 31572049 = 31572246

Showing the first eight; more decompositions exist.
