Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459692, here are decompositions:

13 + 31459679 = 31459692
31 + 31459661 = 31459692
41 + 31459651 = 31459692
59 + 31459633 = 31459692
71 + 31459621 = 31459692
73 + 31459619 = 31459692
83 + 31459609 = 31459692
139 + 31459553 = 31459692

Showing the first eight; more decompositions exist.
