Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594900, here are decompositions:

17 + 31594883 = 31594900
23 + 31594877 = 31594900
89 + 31594811 = 31594900
101 + 31594799 = 31594900
131 + 31594769 = 31594900
173 + 31594727 = 31594900
317 + 31594583 = 31594900
347 + 31594553 = 31594900

Showing the first eight; more decompositions exist.
