Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538034, here are decompositions:

5 + 31538029 = 31538034
37 + 31537997 = 31538034
53 + 31537981 = 31538034
113 + 31537921 = 31538034
131 + 31537903 = 31538034
163 + 31537871 = 31538034
173 + 31537861 = 31538034
191 + 31537843 = 31538034

Showing the first eight; more decompositions exist.
