Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597012, here are decompositions:

89 + 31596923 = 31597012
113 + 31596899 = 31597012
131 + 31596881 = 31597012
173 + 31596839 = 31597012
191 + 31596821 = 31597012
263 + 31596749 = 31597012
269 + 31596743 = 31597012
401 + 31596611 = 31597012

Showing the first eight; more decompositions exist.
