Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459082, here are decompositions:

13 + 31459069 = 31459082
19 + 31459063 = 31459082
181 + 31458901 = 31459082
283 + 31458799 = 31459082
373 + 31458709 = 31459082
379 + 31458703 = 31459082
439 + 31458643 = 31459082
541 + 31458541 = 31459082

Showing the first eight; more decompositions exist.
