Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459302, here are decompositions:

11 + 31459291 = 31459302
13 + 31459289 = 31459302
41 + 31459261 = 31459302
79 + 31459223 = 31459302
101 + 31459201 = 31459302
103 + 31459199 = 31459302
151 + 31459151 = 31459302
179 + 31459123 = 31459302

Showing the first eight; more decompositions exist.
