Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459894, here are decompositions:

3 + 31459891 = 31459894
41 + 31459853 = 31459894
47 + 31459847 = 31459894
197 + 31459697 = 31459894
227 + 31459667 = 31459894
233 + 31459661 = 31459894
353 + 31459541 = 31459894
461 + 31459433 = 31459894

Showing the first eight; more decompositions exist.
