Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596820, here are decompositions:

23 + 31596797 = 31596820
71 + 31596749 = 31596820
107 + 31596713 = 31596820
113 + 31596707 = 31596820
149 + 31596671 = 31596820
347 + 31596473 = 31596820
383 + 31596437 = 31596820
401 + 31596419 = 31596820

Showing the first eight; more decompositions exist.
