Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459326, here are decompositions:

5 + 31459321 = 31459326
37 + 31459289 = 31459326
103 + 31459223 = 31459326
109 + 31459217 = 31459326
127 + 31459199 = 31459326
193 + 31459133 = 31459326
233 + 31459093 = 31459326
257 + 31459069 = 31459326

Showing the first eight; more decompositions exist.
