Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597684, here are decompositions:

11 + 31597673 = 31597684
71 + 31597613 = 31597684
113 + 31597571 = 31597684
191 + 31597493 = 31597684
317 + 31597367 = 31597684
347 + 31597337 = 31597684
401 + 31597283 = 31597684
431 + 31597253 = 31597684

Showing the first eight; more decompositions exist.
