Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595556, here are decompositions:

73 + 31595483 = 31595556
89 + 31595467 = 31595556
149 + 31595407 = 31595556
163 + 31595393 = 31595556
173 + 31595383 = 31595556
193 + 31595363 = 31595556
277 + 31595279 = 31595556
283 + 31595273 = 31595556

Showing the first eight; more decompositions exist.
