Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459360, here are decompositions:

3 + 31459357 = 31459360
11 + 31459349 = 31459360
17 + 31459343 = 31459360
71 + 31459289 = 31459360
137 + 31459223 = 31459360
227 + 31459133 = 31459360
563 + 31458797 = 31459360
599 + 31458761 = 31459360

Showing the first eight; more decompositions exist.
