Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495528, here are decompositions:

5 + 31495523 = 31495528
11 + 31495517 = 31495528
17 + 31495511 = 31495528
47 + 31495481 = 31495528
59 + 31495469 = 31495528
167 + 31495361 = 31495528
419 + 31495109 = 31495528
509 + 31495019 = 31495528

Showing the first eight; more decompositions exist.
