Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467028, here are decompositions:

17 + 31467011 = 31467028
29 + 31466999 = 31467028
59 + 31466969 = 31467028
179 + 31466849 = 31467028
269 + 31466759 = 31467028
401 + 31466627 = 31467028
431 + 31466597 = 31467028
479 + 31466549 = 31467028

Showing the first eight; more decompositions exist.
