Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597548, here are decompositions:

7 + 31597541 = 31597548
41 + 31597507 = 31597548
131 + 31597417 = 31597548
137 + 31597411 = 31597548
181 + 31597367 = 31597548
211 + 31597337 = 31597548
317 + 31597231 = 31597548
349 + 31597199 = 31597548

Showing the first eight; more decompositions exist.
