Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495496, here are decompositions:

3 + 31495493 = 31495496
73 + 31495423 = 31495496
79 + 31495417 = 31495496
139 + 31495357 = 31495496
163 + 31495333 = 31495496
223 + 31495273 = 31495496
283 + 31495213 = 31495496
349 + 31495147 = 31495496

Showing the first eight; more decompositions exist.
