Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534806, here are decompositions:

5 + 31534801 = 31534806
7 + 31534799 = 31534806
19 + 31534787 = 31534806
53 + 31534753 = 31534806
67 + 31534739 = 31534806
97 + 31534709 = 31534806
137 + 31534669 = 31534806
263 + 31534543 = 31534806

Showing the first eight; more decompositions exist.
