Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555176, here are decompositions:

5 + 31555171 = 31555176
19 + 31555157 = 31555176
43 + 31555133 = 31555176
67 + 31555109 = 31555176
83 + 31555093 = 31555176
97 + 31555079 = 31555176
113 + 31555063 = 31555176
157 + 31555019 = 31555176

Showing the first eight; more decompositions exist.
