Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538106, here are decompositions:

43 + 31538063 = 31538106
53 + 31538053 = 31538106
59 + 31538047 = 31538106
73 + 31538033 = 31538106
107 + 31537999 = 31538106
109 + 31537997 = 31538106
167 + 31537939 = 31538106
263 + 31537843 = 31538106

Showing the first eight; more decompositions exist.
