Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595222, here are decompositions:

3 + 31595219 = 31595222
13 + 31595209 = 31595222
163 + 31595059 = 31595222
223 + 31594999 = 31595222
349 + 31594873 = 31595222
409 + 31594813 = 31595222
523 + 31594699 = 31595222
541 + 31594681 = 31595222

Showing the first eight; more decompositions exist.
