Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595764, here are decompositions:

41 + 31595723 = 31595764
47 + 31595717 = 31595764
107 + 31595657 = 31595764
191 + 31595573 = 31595764
197 + 31595567 = 31595764
281 + 31595483 = 31595764
401 + 31595363 = 31595764
491 + 31595273 = 31595764

Showing the first eight; more decompositions exist.
