Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459766, here are decompositions:

7 + 31459759 = 31459766
43 + 31459723 = 31459766
157 + 31459609 = 31459766
367 + 31459399 = 31459766
379 + 31459387 = 31459766
409 + 31459357 = 31459766
643 + 31459123 = 31459766
673 + 31459093 = 31459766

Showing the first eight; more decompositions exist.
