Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459670, here are decompositions:

3 + 31459667 = 31459670
19 + 31459651 = 31459670
37 + 31459633 = 31459670
61 + 31459609 = 31459670
271 + 31459399 = 31459670
283 + 31459387 = 31459670
313 + 31459357 = 31459670
331 + 31459339 = 31459670

Showing the first eight; more decompositions exist.
