Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574896, here are decompositions:

5 + 31574891 = 31574896
47 + 31574849 = 31574896
83 + 31574813 = 31574896
149 + 31574747 = 31574896
173 + 31574723 = 31574896
239 + 31574657 = 31574896
257 + 31574639 = 31574896
389 + 31574507 = 31574896

Showing the first eight; more decompositions exist.
