Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535814, here are decompositions:

5 + 31535809 = 31535814
17 + 31535797 = 31535814
61 + 31535753 = 31535814
67 + 31535747 = 31535814
73 + 31535741 = 31535814
97 + 31535717 = 31535814
157 + 31535657 = 31535814
181 + 31535633 = 31535814

Showing the first eight; more decompositions exist.
