Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597444, here are decompositions:

107 + 31597337 = 31597444
191 + 31597253 = 31597444
293 + 31597151 = 31597444
317 + 31597127 = 31597444
401 + 31597043 = 31597444
467 + 31596977 = 31597444
521 + 31596923 = 31597444
563 + 31596881 = 31597444

Showing the first eight; more decompositions exist.
