Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535834, here are decompositions:

3 + 31535831 = 31535834
7 + 31535827 = 31535834
13 + 31535821 = 31535834
37 + 31535797 = 31535834
163 + 31535671 = 31535834
241 + 31535593 = 31535834
283 + 31535551 = 31535834
331 + 31535503 = 31535834

Showing the first eight; more decompositions exist.
