Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495344, here are decompositions:

11 + 31495333 = 31495344
71 + 31495273 = 31495344
103 + 31495241 = 31495344
131 + 31495213 = 31495344
157 + 31495187 = 31495344
173 + 31495171 = 31495344
191 + 31495153 = 31495344
197 + 31495147 = 31495344

Showing the first eight; more decompositions exist.
