Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459322, here are decompositions:

31 + 31459291 = 31459322
61 + 31459261 = 31459322
199 + 31459123 = 31459322
211 + 31459111 = 31459322
229 + 31459093 = 31459322
409 + 31458913 = 31459322
421 + 31458901 = 31459322
523 + 31458799 = 31459322

Showing the first eight; more decompositions exist.
