Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538076, here are decompositions:

5 + 31538071 = 31538076
13 + 31538063 = 31538076
23 + 31538053 = 31538076
29 + 31538047 = 31538076
43 + 31538033 = 31538076
47 + 31538029 = 31538076
79 + 31537997 = 31538076
137 + 31537939 = 31538076

Showing the first eight; more decompositions exist.
