Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574338, here are decompositions:

11 + 31574327 = 31574338
41 + 31574297 = 31574338
137 + 31574201 = 31574338
239 + 31574099 = 31574338
317 + 31574021 = 31574338
479 + 31573859 = 31574338
491 + 31573847 = 31574338
641 + 31573697 = 31574338

Showing the first eight; more decompositions exist.
