Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595562, here are decompositions:

79 + 31595483 = 31595562
179 + 31595383 = 31595562
191 + 31595371 = 31595562
199 + 31595363 = 31595562
283 + 31595279 = 31595562
311 + 31595251 = 31595562
353 + 31595209 = 31595562
373 + 31595189 = 31595562

Showing the first eight; more decompositions exist.
