Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595854, here are decompositions:

23 + 31595831 = 31595854
47 + 31595807 = 31595854
71 + 31595783 = 31595854
83 + 31595771 = 31595854
131 + 31595723 = 31595854
137 + 31595717 = 31595854
167 + 31595687 = 31595854
197 + 31595657 = 31595854

Showing the first eight; more decompositions exist.
