Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597030, here are decompositions:

53 + 31596977 = 31597030
107 + 31596923 = 31597030
131 + 31596899 = 31597030
149 + 31596881 = 31597030
173 + 31596857 = 31597030
191 + 31596839 = 31597030
233 + 31596797 = 31597030
281 + 31596749 = 31597030

Showing the first eight; more decompositions exist.
