Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538796, here are decompositions:

7 + 31538789 = 31538796
17 + 31538779 = 31538796
43 + 31538753 = 31538796
53 + 31538743 = 31538796
67 + 31538729 = 31538796
83 + 31538713 = 31538796
103 + 31538693 = 31538796
167 + 31538629 = 31538796

Showing the first eight; more decompositions exist.
