Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554408, here are decompositions:

7 + 31554401 = 31554408
47 + 31554361 = 31554408
71 + 31554337 = 31554408
167 + 31554241 = 31554408
227 + 31554181 = 31554408
229 + 31554179 = 31554408
331 + 31554077 = 31554408
397 + 31554011 = 31554408

Showing the first eight; more decompositions exist.
