Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468546, here are decompositions:

3 + 31468543 = 31468546
17 + 31468529 = 31468546
23 + 31468523 = 31468546
29 + 31468517 = 31468546
47 + 31468499 = 31468546
149 + 31468397 = 31468546
227 + 31468319 = 31468546
257 + 31468289 = 31468546

Showing the first eight; more decompositions exist.
