Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554354, here are decompositions:

17 + 31554337 = 31554354
67 + 31554287 = 31554354
71 + 31554283 = 31554354
113 + 31554241 = 31554354
173 + 31554181 = 31554354
191 + 31554163 = 31554354
193 + 31554161 = 31554354
211 + 31554143 = 31554354

Showing the first eight; more decompositions exist.
