Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467328, here are decompositions:

17 + 31467311 = 31467328
239 + 31467089 = 31467328
257 + 31467071 = 31467328
317 + 31467011 = 31467328
359 + 31466969 = 31467328
461 + 31466867 = 31467328
479 + 31466849 = 31467328
569 + 31466759 = 31467328

Showing the first eight; more decompositions exist.
