Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607044, here are decompositions:

5 + 31607039 = 31607044
47 + 31606997 = 31607044
71 + 31606973 = 31607044
101 + 31606943 = 31607044
113 + 31606931 = 31607044
197 + 31606847 = 31607044
233 + 31606811 = 31607044
317 + 31606727 = 31607044

Showing the first eight; more decompositions exist.
