Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607098, here are decompositions:

11 + 31607087 = 31607098
59 + 31607039 = 31607098
101 + 31606997 = 31607098
167 + 31606931 = 31607098
179 + 31606919 = 31607098
251 + 31606847 = 31607098
269 + 31606829 = 31607098
401 + 31606697 = 31607098

Showing the first eight; more decompositions exist.
