Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596530, here are decompositions:

19 + 31596511 = 31596530
127 + 31596403 = 31596530
139 + 31596391 = 31596530
151 + 31596379 = 31596530
223 + 31596307 = 31596530
337 + 31596193 = 31596530
367 + 31596163 = 31596530
379 + 31596151 = 31596530

Showing the first eight; more decompositions exist.
