Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600884, here are decompositions:

23 + 31600861 = 31600884
41 + 31600843 = 31600884
61 + 31600823 = 31600884
67 + 31600817 = 31600884
83 + 31600801 = 31600884
101 + 31600783 = 31600884
113 + 31600771 = 31600884
131 + 31600753 = 31600884

Showing the first eight; more decompositions exist.
