Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459226, here are decompositions:

3 + 31459223 = 31459226
103 + 31459123 = 31459226
157 + 31459069 = 31459226
163 + 31459063 = 31459226
313 + 31458913 = 31459226
397 + 31458829 = 31459226
439 + 31458787 = 31459226
523 + 31458703 = 31459226

Showing the first eight; more decompositions exist.
