Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554252, here are decompositions:

11 + 31554241 = 31554252
53 + 31554199 = 31554252
71 + 31554181 = 31554252
73 + 31554179 = 31554252
89 + 31554163 = 31554252
109 + 31554143 = 31554252
131 + 31554121 = 31554252
179 + 31554073 = 31554252

Showing the first eight; more decompositions exist.
