Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597506, here are decompositions:

13 + 31597493 = 31597506
23 + 31597483 = 31597506
53 + 31597453 = 31597506
89 + 31597417 = 31597506
139 + 31597367 = 31597506
223 + 31597283 = 31597506
263 + 31597243 = 31597506
293 + 31597213 = 31597506

Showing the first eight; more decompositions exist.
