Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467500, here are decompositions:

3 + 31467497 = 31467500
19 + 31467481 = 31467500
67 + 31467433 = 31467500
199 + 31467301 = 31467500
241 + 31467259 = 31467500
271 + 31467229 = 31467500
331 + 31467169 = 31467500
367 + 31467133 = 31467500

Showing the first eight; more decompositions exist.
