Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459254, here are decompositions:

31 + 31459223 = 31459254
37 + 31459217 = 31459254
53 + 31459201 = 31459254
103 + 31459151 = 31459254
131 + 31459123 = 31459254
181 + 31459073 = 31459254
191 + 31459063 = 31459254
223 + 31459031 = 31459254

Showing the first eight; more decompositions exist.
