Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472266, here are decompositions:

5 + 31472261 = 31472266
83 + 31472183 = 31472266
107 + 31472159 = 31472266
113 + 31472153 = 31472266
197 + 31472069 = 31472266
263 + 31472003 = 31472266
359 + 31471907 = 31472266
383 + 31471883 = 31472266

Showing the first eight; more decompositions exist.
