Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534038, here are decompositions:

5 + 31534033 = 31534038
59 + 31533979 = 31534038
71 + 31533967 = 31534038
79 + 31533959 = 31534038
89 + 31533949 = 31534038
127 + 31533911 = 31534038
167 + 31533871 = 31534038
191 + 31533847 = 31534038

Showing the first eight; more decompositions exist.
