Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595502, here are decompositions:

19 + 31595483 = 31595502
109 + 31595393 = 31595502
131 + 31595371 = 31595502
139 + 31595363 = 31595502
223 + 31595279 = 31595502
229 + 31595273 = 31595502
251 + 31595251 = 31595502
283 + 31595219 = 31595502

Showing the first eight; more decompositions exist.
