Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570632, here are decompositions:

13 + 31570619 = 31570632
19 + 31570613 = 31570632
29 + 31570603 = 31570632
113 + 31570519 = 31570632
131 + 31570501 = 31570632
151 + 31570481 = 31570632
173 + 31570459 = 31570632
241 + 31570391 = 31570632

Showing the first eight; more decompositions exist.
