Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459396, here are decompositions:

47 + 31459349 = 31459396
53 + 31459343 = 31459396
107 + 31459289 = 31459396
173 + 31459223 = 31459396
179 + 31459217 = 31459396
197 + 31459199 = 31459396
263 + 31459133 = 31459396
443 + 31458953 = 31459396

Showing the first eight; more decompositions exist.
