Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495468, here are decompositions:

5 + 31495463 = 31495468
101 + 31495367 = 31495468
107 + 31495361 = 31495468
227 + 31495241 = 31495468
269 + 31495199 = 31495468
281 + 31495187 = 31495468
311 + 31495157 = 31495468
359 + 31495109 = 31495468

Showing the first eight; more decompositions exist.
