Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541674, here are decompositions:

23 + 31541651 = 31541674
41 + 31541633 = 31541674
83 + 31541591 = 31541674
167 + 31541507 = 31541674
191 + 31541483 = 31541674
257 + 31541417 = 31541674
431 + 31541243 = 31541674
557 + 31541117 = 31541674

Showing the first eight; more decompositions exist.
