Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607826, here are decompositions:

37 + 31607789 = 31607826
43 + 31607783 = 31607826
79 + 31607747 = 31607826
109 + 31607717 = 31607826
137 + 31607689 = 31607826
139 + 31607687 = 31607826
197 + 31607629 = 31607826
227 + 31607599 = 31607826

Showing the first eight; more decompositions exist.
