Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459292, here are decompositions:

3 + 31459289 = 31459292
31 + 31459261 = 31459292
181 + 31459111 = 31459292
199 + 31459093 = 31459292
223 + 31459069 = 31459292
229 + 31459063 = 31459292
379 + 31458913 = 31459292
463 + 31458829 = 31459292

Showing the first eight; more decompositions exist.
