Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574832, here are decompositions:

11 + 31574821 = 31574832
19 + 31574813 = 31574832
53 + 31574779 = 31574832
59 + 31574773 = 31574832
109 + 31574723 = 31574832
131 + 31574701 = 31574832
139 + 31574693 = 31574832
151 + 31574681 = 31574832

Showing the first eight; more decompositions exist.
