Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459282, here are decompositions:

59 + 31459223 = 31459282
83 + 31459199 = 31459282
131 + 31459151 = 31459282
149 + 31459133 = 31459282
251 + 31459031 = 31459282
263 + 31459019 = 31459282
359 + 31458923 = 31459282
419 + 31458863 = 31459282

Showing the first eight; more decompositions exist.
