Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557016, here are decompositions:

3 + 31557013 = 31557016
5 + 31557011 = 31557016
59 + 31556957 = 31557016
107 + 31556909 = 31557016
269 + 31556747 = 31557016
479 + 31556537 = 31557016
593 + 31556423 = 31557016
599 + 31556417 = 31557016

Showing the first eight; more decompositions exist.
