Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462806, here are decompositions:

13 + 31462793 = 31462806
47 + 31462759 = 31462806
59 + 31462747 = 31462806
83 + 31462723 = 31462806
157 + 31462649 = 31462806
197 + 31462609 = 31462806
223 + 31462583 = 31462806
227 + 31462579 = 31462806

Showing the first eight; more decompositions exist.
