Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585202, here are decompositions:

3 + 31585199 = 31585202
13 + 31585189 = 31585202
31 + 31585171 = 31585202
43 + 31585159 = 31585202
109 + 31585093 = 31585202
241 + 31584961 = 31585202
349 + 31584853 = 31585202
373 + 31584829 = 31585202

Showing the first eight; more decompositions exist.
