Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495296, here are decompositions:

23 + 31495273 = 31495296
83 + 31495213 = 31495296
97 + 31495199 = 31495296
109 + 31495187 = 31495296
139 + 31495157 = 31495296
149 + 31495147 = 31495296
179 + 31495117 = 31495296
233 + 31495063 = 31495296

Showing the first eight; more decompositions exist.
