Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482826, here are decompositions:

3 + 31482823 = 31482826
5 + 31482821 = 31482826
47 + 31482779 = 31482826
83 + 31482743 = 31482826
227 + 31482599 = 31482826
239 + 31482587 = 31482826
257 + 31482569 = 31482826
317 + 31482509 = 31482826

Showing the first eight; more decompositions exist.
