Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459464, here are decompositions:

7 + 31459457 = 31459464
31 + 31459433 = 31459464
107 + 31459357 = 31459464
173 + 31459291 = 31459464
241 + 31459223 = 31459464
263 + 31459201 = 31459464
313 + 31459151 = 31459464
331 + 31459133 = 31459464

Showing the first eight; more decompositions exist.
