Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459704, here are decompositions:

7 + 31459697 = 31459704
37 + 31459667 = 31459704
43 + 31459661 = 31459704
53 + 31459651 = 31459704
71 + 31459633 = 31459704
83 + 31459621 = 31459704
151 + 31459553 = 31459704
163 + 31459541 = 31459704

Showing the first eight; more decompositions exist.
