Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459562, here are decompositions:

163 + 31459399 = 31459562
223 + 31459339 = 31459562
241 + 31459321 = 31459562
271 + 31459291 = 31459562
439 + 31459123 = 31459562
499 + 31459063 = 31459562
661 + 31458901 = 31459562
733 + 31458829 = 31459562

Showing the first eight; more decompositions exist.
