Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459342, here are decompositions:

3 + 31459339 = 31459342
53 + 31459289 = 31459342
191 + 31459151 = 31459342
269 + 31459073 = 31459342
311 + 31459031 = 31459342
359 + 31458983 = 31459342
389 + 31458953 = 31459342
419 + 31458923 = 31459342

Showing the first eight; more decompositions exist.
