Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459312, here are decompositions:

23 + 31459289 = 31459312
89 + 31459223 = 31459312
113 + 31459199 = 31459312
179 + 31459133 = 31459312
239 + 31459073 = 31459312
281 + 31459031 = 31459312
293 + 31459019 = 31459312
359 + 31458953 = 31459312

Showing the first eight; more decompositions exist.
