Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538070, here are decompositions:

7 + 31538063 = 31538070
17 + 31538053 = 31538070
23 + 31538047 = 31538070
37 + 31538033 = 31538070
41 + 31538029 = 31538070
71 + 31537999 = 31538070
73 + 31537997 = 31538070
89 + 31537981 = 31538070

Showing the first eight; more decompositions exist.
