Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607488, here are decompositions:

41 + 31607447 = 31607488
89 + 31607399 = 31607488
131 + 31607357 = 31607488
179 + 31607309 = 31607488
191 + 31607297 = 31607488
197 + 31607291 = 31607488
251 + 31607237 = 31607488
281 + 31607207 = 31607488

Showing the first eight; more decompositions exist.
