Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595346, here are decompositions:

67 + 31595279 = 31595346
73 + 31595273 = 31595346
103 + 31595243 = 31595346
109 + 31595237 = 31595346
127 + 31595219 = 31595346
137 + 31595209 = 31595346
157 + 31595189 = 31595346
173 + 31595173 = 31595346

Showing the first eight; more decompositions exist.
