Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574326, here are decompositions:

23 + 31574303 = 31574326
29 + 31574297 = 31574326
227 + 31574099 = 31574326
233 + 31574093 = 31574326
359 + 31573967 = 31574326
467 + 31573859 = 31574326
479 + 31573847 = 31574326
503 + 31573823 = 31574326

Showing the first eight; more decompositions exist.
