Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595744, here are decompositions:

13 + 31595731 = 31595744
43 + 31595701 = 31595744
73 + 31595671 = 31595744
151 + 31595593 = 31595744
163 + 31595581 = 31595744
277 + 31595467 = 31595744
337 + 31595407 = 31595744
373 + 31595371 = 31595744

Showing the first eight; more decompositions exist.
