Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574212, here are decompositions:

11 + 31574201 = 31574212
113 + 31574099 = 31574212
191 + 31574021 = 31574212
251 + 31573961 = 31574212
281 + 31573931 = 31574212
353 + 31573859 = 31574212
359 + 31573853 = 31574212
389 + 31573823 = 31574212

Showing the first eight; more decompositions exist.
