Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471424, here are decompositions:

13 + 31471411 = 31471424
37 + 31471387 = 31471424
67 + 31471357 = 31471424
211 + 31471213 = 31471424
277 + 31471147 = 31471424
331 + 31471093 = 31471424
373 + 31471051 = 31471424
433 + 31470991 = 31471424

Showing the first eight; more decompositions exist.
