Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595774, here are decompositions:

3 + 31595771 = 31595774
43 + 31595731 = 31595774
73 + 31595701 = 31595774
103 + 31595671 = 31595774
163 + 31595611 = 31595774
181 + 31595593 = 31595774
193 + 31595581 = 31595774
307 + 31595467 = 31595774

Showing the first eight; more decompositions exist.
