Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597876, here are decompositions:

3 + 31597873 = 31597876
53 + 31597823 = 31597876
83 + 31597793 = 31597876
113 + 31597763 = 31597876
137 + 31597739 = 31597876
179 + 31597697 = 31597876
263 + 31597613 = 31597876
383 + 31597493 = 31597876

Showing the first eight; more decompositions exist.
