Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495534, here are decompositions:

11 + 31495523 = 31495534
17 + 31495517 = 31495534
23 + 31495511 = 31495534
41 + 31495493 = 31495534
53 + 31495481 = 31495534
71 + 31495463 = 31495534
131 + 31495403 = 31495534
167 + 31495367 = 31495534

Showing the first eight; more decompositions exist.
