Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555324, here are decompositions:

5 + 31555319 = 31555324
11 + 31555313 = 31555324
71 + 31555253 = 31555324
113 + 31555211 = 31555324
137 + 31555187 = 31555324
167 + 31555157 = 31555324
191 + 31555133 = 31555324
263 + 31555061 = 31555324

Showing the first eight; more decompositions exist.
