Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538052, here are decompositions:

5 + 31538047 = 31538052
19 + 31538033 = 31538052
23 + 31538029 = 31538052
53 + 31537999 = 31538052
71 + 31537981 = 31538052
113 + 31537939 = 31538052
131 + 31537921 = 31538052
149 + 31537903 = 31538052

Showing the first eight; more decompositions exist.
