Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607548, here are decompositions:

17 + 31607531 = 31607548
59 + 31607489 = 31607548
101 + 31607447 = 31607548
149 + 31607399 = 31607548
191 + 31607357 = 31607548
239 + 31607309 = 31607548
251 + 31607297 = 31607548
257 + 31607291 = 31607548

Showing the first eight; more decompositions exist.
