Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467284, here are decompositions:

103 + 31467181 = 31467284
127 + 31467157 = 31467284
151 + 31467133 = 31467284
157 + 31467127 = 31467284
181 + 31467103 = 31467284
307 + 31466977 = 31467284
463 + 31466821 = 31467284
571 + 31466713 = 31467284

Showing the first eight; more decompositions exist.
