Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509054, here are decompositions:

23 + 31509031 = 31509054
37 + 31509017 = 31509054
107 + 31508947 = 31509054
167 + 31508887 = 31509054
191 + 31508863 = 31509054
197 + 31508857 = 31509054
211 + 31508843 = 31509054
263 + 31508791 = 31509054

Showing the first eight; more decompositions exist.
