Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538038, here are decompositions:

5 + 31538033 = 31538038
41 + 31537997 = 31538038
149 + 31537889 = 31538038
167 + 31537871 = 31538038
179 + 31537859 = 31538038
317 + 31537721 = 31538038
347 + 31537691 = 31538038
479 + 31537559 = 31538038

Showing the first eight; more decompositions exist.
