Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495498, here are decompositions:

5 + 31495493 = 31495498
17 + 31495481 = 31495498
29 + 31495469 = 31495498
131 + 31495367 = 31495498
137 + 31495361 = 31495498
257 + 31495241 = 31495498
311 + 31495187 = 31495498
389 + 31495109 = 31495498

Showing the first eight; more decompositions exist.
