Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475434, here are decompositions:

5 + 31475429 = 31475434
41 + 31475393 = 31475434
47 + 31475387 = 31475434
113 + 31475321 = 31475434
191 + 31475243 = 31475434
293 + 31475141 = 31475434
503 + 31474931 = 31475434
701 + 31474733 = 31475434

Showing the first eight; more decompositions exist.
