Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467244, here are decompositions:

41 + 31467203 = 31467244
173 + 31467071 = 31467244
233 + 31467011 = 31467244
251 + 31466993 = 31467244
293 + 31466951 = 31467244
311 + 31466933 = 31467244
491 + 31466753 = 31467244
587 + 31466657 = 31467244

Showing the first eight; more decompositions exist.
