Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596038, here are decompositions:

31 + 31596007 = 31596038
109 + 31595929 = 31596038
157 + 31595881 = 31596038
307 + 31595731 = 31596038
337 + 31595701 = 31596038
367 + 31595671 = 31596038
457 + 31595581 = 31596038
571 + 31595467 = 31596038

Showing the first eight; more decompositions exist.
