Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459954, here are decompositions:

5 + 31459949 = 31459954
17 + 31459937 = 31459954
23 + 31459931 = 31459954
101 + 31459853 = 31459954
107 + 31459847 = 31459954
257 + 31459697 = 31459954
293 + 31459661 = 31459954
401 + 31459553 = 31459954

Showing the first eight; more decompositions exist.
