Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574716, here are decompositions:

23 + 31574693 = 31574716
29 + 31574687 = 31574716
59 + 31574657 = 31574716
227 + 31574489 = 31574716
263 + 31574453 = 31574716
347 + 31574369 = 31574716
353 + 31574363 = 31574716
389 + 31574327 = 31574716

Showing the first eight; more decompositions exist.
