Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459898, here are decompositions:

7 + 31459891 = 31459898
139 + 31459759 = 31459898
181 + 31459717 = 31459898
277 + 31459621 = 31459898
499 + 31459399 = 31459898
541 + 31459357 = 31459898
577 + 31459321 = 31459898
607 + 31459291 = 31459898

Showing the first eight; more decompositions exist.
