Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459344, here are decompositions:

5 + 31459339 = 31459344
23 + 31459321 = 31459344
53 + 31459291 = 31459344
83 + 31459261 = 31459344
127 + 31459217 = 31459344
193 + 31459151 = 31459344
211 + 31459133 = 31459344
233 + 31459111 = 31459344

Showing the first eight; more decompositions exist.
