Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459022, here are decompositions:

3 + 31459019 = 31459022
109 + 31458913 = 31459022
193 + 31458829 = 31459022
223 + 31458799 = 31459022
313 + 31458709 = 31459022
379 + 31458643 = 31459022
421 + 31458601 = 31459022
433 + 31458589 = 31459022

Showing the first eight; more decompositions exist.
