Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485796, here are decompositions:

5 + 31485791 = 31485796
29 + 31485767 = 31485796
47 + 31485749 = 31485796
53 + 31485743 = 31485796
59 + 31485737 = 31485796
197 + 31485599 = 31485796
263 + 31485533 = 31485796
347 + 31485449 = 31485796

Showing the first eight; more decompositions exist.
