Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627144, here are decompositions:

11 + 31627133 = 31627144
23 + 31627121 = 31627144
53 + 31627091 = 31627144
71 + 31627073 = 31627144
137 + 31627007 = 31627144
167 + 31626977 = 31627144
251 + 31626893 = 31627144
317 + 31626827 = 31627144

Showing the first eight; more decompositions exist.
