Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475446, here are decompositions:

3 + 31475443 = 31475446
17 + 31475429 = 31475446
53 + 31475393 = 31475446
59 + 31475387 = 31475446
257 + 31475189 = 31475446
347 + 31475099 = 31475446
449 + 31474997 = 31475446
617 + 31474829 = 31475446

Showing the first eight; more decompositions exist.
