Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574344, here are decompositions:

17 + 31574327 = 31574344
41 + 31574303 = 31574344
47 + 31574297 = 31574344
83 + 31574261 = 31574344
251 + 31574093 = 31574344
383 + 31573961 = 31574344
491 + 31573853 = 31574344
521 + 31573823 = 31574344

Showing the first eight; more decompositions exist.
