Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471402, here are decompositions:

5 + 31471397 = 31471402
29 + 31471373 = 31471402
41 + 31471361 = 31471402
71 + 31471331 = 31471402
113 + 31471289 = 31471402
293 + 31471109 = 31471402
311 + 31471091 = 31471402
359 + 31471043 = 31471402

Showing the first eight; more decompositions exist.
