Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595340, here are decompositions:

61 + 31595279 = 31595340
67 + 31595273 = 31595340
89 + 31595251 = 31595340
97 + 31595243 = 31595340
103 + 31595237 = 31595340
131 + 31595209 = 31595340
151 + 31595189 = 31595340
163 + 31595177 = 31595340

Showing the first eight; more decompositions exist.
