Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467668, here are decompositions:

79 + 31467589 = 31467668
97 + 31467571 = 31467668
109 + 31467559 = 31467668
367 + 31467301 = 31467668
409 + 31467259 = 31467668
439 + 31467229 = 31467668
487 + 31467181 = 31467668
499 + 31467169 = 31467668

Showing the first eight; more decompositions exist.
