Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557676, here are decompositions:

5 + 31557671 = 31557676
107 + 31557569 = 31557676
113 + 31557563 = 31557676
167 + 31557509 = 31557676
173 + 31557503 = 31557676
197 + 31557479 = 31557676
233 + 31557443 = 31557676
239 + 31557437 = 31557676

Showing the first eight; more decompositions exist.
