Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557596, here are decompositions:

43 + 31557553 = 31557596
67 + 31557529 = 31557596
73 + 31557523 = 31557596
163 + 31557433 = 31557596
229 + 31557367 = 31557596
313 + 31557283 = 31557596
349 + 31557247 = 31557596
379 + 31557217 = 31557596

Showing the first eight; more decompositions exist.
