Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555096, here are decompositions:

3 + 31555093 = 31555096
17 + 31555079 = 31555096
149 + 31554947 = 31555096
197 + 31554899 = 31555096
233 + 31554863 = 31555096
347 + 31554749 = 31555096
479 + 31554617 = 31555096
557 + 31554539 = 31555096

Showing the first eight; more decompositions exist.
