Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460080, here are decompositions:

17 + 31460063 = 31460080
131 + 31459949 = 31460080
149 + 31459931 = 31460080
227 + 31459853 = 31460080
233 + 31459847 = 31460080
251 + 31459829 = 31460080
347 + 31459733 = 31460080
383 + 31459697 = 31460080

Showing the first eight; more decompositions exist.
