Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459698, here are decompositions:

19 + 31459679 = 31459698
31 + 31459667 = 31459698
37 + 31459661 = 31459698
47 + 31459651 = 31459698
79 + 31459619 = 31459698
89 + 31459609 = 31459698
157 + 31459541 = 31459698
181 + 31459517 = 31459698

Showing the first eight; more decompositions exist.
