Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570846, here are decompositions:

3 + 31570843 = 31570846
17 + 31570829 = 31570846
29 + 31570817 = 31570846
59 + 31570787 = 31570846
89 + 31570757 = 31570846
137 + 31570709 = 31570846
173 + 31570673 = 31570846
179 + 31570667 = 31570846

Showing the first eight; more decompositions exist.
