Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467276, here are decompositions:

17 + 31467259 = 31467276
47 + 31467229 = 31467276
73 + 31467203 = 31467276
107 + 31467169 = 31467276
109 + 31467167 = 31467276
149 + 31467127 = 31467276
173 + 31467103 = 31467276
193 + 31467083 = 31467276

Showing the first eight; more decompositions exist.
