Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495326, here are decompositions:

53 + 31495273 = 31495326
113 + 31495213 = 31495326
127 + 31495199 = 31495326
139 + 31495187 = 31495326
173 + 31495153 = 31495326
179 + 31495147 = 31495326
263 + 31495063 = 31495326
283 + 31495043 = 31495326

Showing the first eight; more decompositions exist.
