Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596122, here are decompositions:

3 + 31596119 = 31596122
73 + 31596049 = 31596122
139 + 31595983 = 31596122
193 + 31595929 = 31596122
241 + 31595881 = 31596122
421 + 31595701 = 31596122
541 + 31595581 = 31596122
739 + 31595383 = 31596122

Showing the first eight; more decompositions exist.
