Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574706, here are decompositions:

5 + 31574701 = 31574706
13 + 31574693 = 31574706
17 + 31574689 = 31574706
19 + 31574687 = 31574706
29 + 31574677 = 31574706
67 + 31574639 = 31574706
199 + 31574507 = 31574706
227 + 31574479 = 31574706

Showing the first eight; more decompositions exist.
