Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459270, here are decompositions:

47 + 31459223 = 31459270
53 + 31459217 = 31459270
71 + 31459199 = 31459270
137 + 31459133 = 31459270
197 + 31459073 = 31459270
239 + 31459031 = 31459270
251 + 31459019 = 31459270
317 + 31458953 = 31459270

Showing the first eight; more decompositions exist.
