Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574332, here are decompositions:

3 + 31574329 = 31574332
5 + 31574327 = 31574332
29 + 31574303 = 31574332
71 + 31574261 = 31574332
131 + 31574201 = 31574332
233 + 31574099 = 31574332
239 + 31574093 = 31574332
311 + 31574021 = 31574332

Showing the first eight; more decompositions exist.
