Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597482, here are decompositions:

11 + 31597471 = 31597482
29 + 31597453 = 31597482
71 + 31597411 = 31597482
199 + 31597283 = 31597482
229 + 31597253 = 31597482
239 + 31597243 = 31597482
251 + 31597231 = 31597482
269 + 31597213 = 31597482

Showing the first eight; more decompositions exist.
