Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459556, here are decompositions:

3 + 31459553 = 31459556
157 + 31459399 = 31459556
199 + 31459357 = 31459556
433 + 31459123 = 31459556
463 + 31459093 = 31459556
487 + 31459069 = 31459556
619 + 31458937 = 31459556
643 + 31458913 = 31459556

Showing the first eight; more decompositions exist.
