Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595844, here are decompositions:

11 + 31595833 = 31595844
13 + 31595831 = 31595844
37 + 31595807 = 31595844
61 + 31595783 = 31595844
67 + 31595777 = 31595844
73 + 31595771 = 31595844
113 + 31595731 = 31595844
127 + 31595717 = 31595844

Showing the first eight; more decompositions exist.
