Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459852, here are decompositions:

3 + 31459849 = 31459852
5 + 31459847 = 31459852
23 + 31459829 = 31459852
173 + 31459679 = 31459852
191 + 31459661 = 31459852
233 + 31459619 = 31459852
311 + 31459541 = 31459852
353 + 31459499 = 31459852

Showing the first eight; more decompositions exist.
