Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471414, here are decompositions:

3 + 31471411 = 31471414
17 + 31471397 = 31471414
41 + 31471373 = 31471414
53 + 31471361 = 31471414
83 + 31471331 = 31471414
197 + 31471217 = 31471414
383 + 31471031 = 31471414
461 + 31470953 = 31471414

Showing the first eight; more decompositions exist.
