Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535844, here are decompositions:

13 + 31535831 = 31535844
17 + 31535827 = 31535844
23 + 31535821 = 31535844
47 + 31535797 = 31535844
97 + 31535747 = 31535844
103 + 31535741 = 31535844
127 + 31535717 = 31535844
163 + 31535681 = 31535844

Showing the first eight; more decompositions exist.
