Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597476, here are decompositions:

5 + 31597471 = 31597476
23 + 31597453 = 31597476
59 + 31597417 = 31597476
109 + 31597367 = 31597476
139 + 31597337 = 31597476
193 + 31597283 = 31597476
223 + 31597253 = 31597476
233 + 31597243 = 31597476

Showing the first eight; more decompositions exist.
