Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519266, here are decompositions:

13 + 31519253 = 31519266
19 + 31519247 = 31519266
67 + 31519199 = 31519266
73 + 31519193 = 31519266
157 + 31519109 = 31519266
167 + 31519099 = 31519266
193 + 31519073 = 31519266
197 + 31519069 = 31519266

Showing the first eight; more decompositions exist.
