Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495522, here are decompositions:

5 + 31495517 = 31495522
11 + 31495511 = 31495522
29 + 31495493 = 31495522
41 + 31495481 = 31495522
53 + 31495469 = 31495522
59 + 31495463 = 31495522
281 + 31495241 = 31495522
479 + 31495043 = 31495522

Showing the first eight; more decompositions exist.
