Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597546, here are decompositions:

5 + 31597541 = 31597546
53 + 31597493 = 31597546
179 + 31597367 = 31597546
263 + 31597283 = 31597546
293 + 31597253 = 31597546
347 + 31597199 = 31597546
419 + 31597127 = 31597546
503 + 31597043 = 31597546

Showing the first eight; more decompositions exist.
