Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495482, here are decompositions:

13 + 31495469 = 31495482
19 + 31495463 = 31495482
59 + 31495423 = 31495482
79 + 31495403 = 31495482
131 + 31495351 = 31495482
149 + 31495333 = 31495482
241 + 31495241 = 31495482
269 + 31495213 = 31495482

Showing the first eight; more decompositions exist.
