Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452796, here are decompositions:

3 + 31452793 = 31452796
47 + 31452749 = 31452796
113 + 31452683 = 31452796
173 + 31452623 = 31452796
197 + 31452599 = 31452796
257 + 31452539 = 31452796
269 + 31452527 = 31452796
563 + 31452233 = 31452796

Showing the first eight; more decompositions exist.
