Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538082, here are decompositions:

11 + 31538071 = 31538082
19 + 31538063 = 31538082
29 + 31538053 = 31538082
53 + 31538029 = 31538082
83 + 31537999 = 31538082
101 + 31537981 = 31538082
179 + 31537903 = 31538082
193 + 31537889 = 31538082

Showing the first eight; more decompositions exist.
