Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459274, here are decompositions:

13 + 31459261 = 31459274
73 + 31459201 = 31459274
151 + 31459123 = 31459274
163 + 31459111 = 31459274
181 + 31459093 = 31459274
211 + 31459063 = 31459274
307 + 31458967 = 31459274
337 + 31458937 = 31459274

Showing the first eight; more decompositions exist.
