Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554246, here are decompositions:

5 + 31554241 = 31554246
47 + 31554199 = 31554246
67 + 31554179 = 31554246
83 + 31554163 = 31554246
103 + 31554143 = 31554246
173 + 31554073 = 31554246
233 + 31554013 = 31554246
263 + 31553983 = 31554246

Showing the first eight; more decompositions exist.
