Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595358, here are decompositions:

79 + 31595279 = 31595358
107 + 31595251 = 31595358
139 + 31595219 = 31595358
149 + 31595209 = 31595358
181 + 31595177 = 31595358
257 + 31595101 = 31595358
337 + 31595021 = 31595358
349 + 31595009 = 31595358

Showing the first eight; more decompositions exist.
