Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574122, here are decompositions:

23 + 31574099 = 31574122
29 + 31574093 = 31574122
101 + 31574021 = 31574122
191 + 31573931 = 31574122
263 + 31573859 = 31574122
269 + 31573853 = 31574122
443 + 31573679 = 31574122
479 + 31573643 = 31574122

Showing the first eight; more decompositions exist.
