Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459674, here are decompositions:

7 + 31459667 = 31459674
13 + 31459661 = 31459674
23 + 31459651 = 31459674
41 + 31459633 = 31459674
53 + 31459621 = 31459674
157 + 31459517 = 31459674
241 + 31459433 = 31459674
317 + 31459357 = 31459674

Showing the first eight; more decompositions exist.
