Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471434, here are decompositions:

23 + 31471411 = 31471434
37 + 31471397 = 31471434
47 + 31471387 = 31471434
61 + 31471373 = 31471434
73 + 31471361 = 31471434
103 + 31471331 = 31471434
227 + 31471207 = 31471434
263 + 31471171 = 31471434

Showing the first eight; more decompositions exist.
