Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459314, here are decompositions:

23 + 31459291 = 31459314
53 + 31459261 = 31459314
97 + 31459217 = 31459314
113 + 31459201 = 31459314
163 + 31459151 = 31459314
181 + 31459133 = 31459314
191 + 31459123 = 31459314
241 + 31459073 = 31459314

Showing the first eight; more decompositions exist.
