Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597102, here are decompositions:

3 + 31597099 = 31597102
59 + 31597043 = 31597102
71 + 31597031 = 31597102
179 + 31596923 = 31597102
263 + 31596839 = 31597102
281 + 31596821 = 31597102
353 + 31596749 = 31597102
359 + 31596743 = 31597102

Showing the first eight; more decompositions exist.
