Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538838, here are decompositions:

11 + 31538827 = 31538838
31 + 31538807 = 31538838
59 + 31538779 = 31538838
109 + 31538729 = 31538838
127 + 31538711 = 31538838
167 + 31538671 = 31538838
197 + 31538641 = 31538838
257 + 31538581 = 31538838

Showing the first eight; more decompositions exist.
