Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554294, here are decompositions:

7 + 31554287 = 31554294
11 + 31554283 = 31554294
53 + 31554241 = 31554294
113 + 31554181 = 31554294
131 + 31554163 = 31554294
151 + 31554143 = 31554294
173 + 31554121 = 31554294
251 + 31554043 = 31554294

Showing the first eight; more decompositions exist.
