Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459306, here are decompositions:

17 + 31459289 = 31459306
83 + 31459223 = 31459306
89 + 31459217 = 31459306
107 + 31459199 = 31459306
173 + 31459133 = 31459306
233 + 31459073 = 31459306
353 + 31458953 = 31459306
383 + 31458923 = 31459306

Showing the first eight; more decompositions exist.
