Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574824, here are decompositions:

3 + 31574821 = 31574824
11 + 31574813 = 31574824
101 + 31574723 = 31574824
131 + 31574693 = 31574824
137 + 31574687 = 31574824
167 + 31574657 = 31574824
293 + 31574531 = 31574824
317 + 31574507 = 31574824

Showing the first eight; more decompositions exist.
