Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459324, here are decompositions:

3 + 31459321 = 31459324
101 + 31459223 = 31459324
107 + 31459217 = 31459324
173 + 31459151 = 31459324
191 + 31459133 = 31459324
251 + 31459073 = 31459324
293 + 31459031 = 31459324
401 + 31458923 = 31459324

Showing the first eight; more decompositions exist.
