Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595796, here are decompositions:

13 + 31595783 = 31595796
19 + 31595777 = 31595796
73 + 31595723 = 31595796
79 + 31595717 = 31595796
109 + 31595687 = 31595796
139 + 31595657 = 31595796
223 + 31595573 = 31595796
227 + 31595569 = 31595796

Showing the first eight; more decompositions exist.
