Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467824, here are decompositions:

13 + 31467811 = 31467824
61 + 31467763 = 31467824
97 + 31467727 = 31467824
103 + 31467721 = 31467824
457 + 31467367 = 31467824
523 + 31467301 = 31467824
643 + 31467181 = 31467824
691 + 31467133 = 31467824

Showing the first eight; more decompositions exist.
