Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467290, here are decompositions:

31 + 31467259 = 31467290
61 + 31467229 = 31467290
109 + 31467181 = 31467290
157 + 31467133 = 31467290
163 + 31467127 = 31467290
223 + 31467067 = 31467290
313 + 31466977 = 31467290
397 + 31466893 = 31467290

Showing the first eight; more decompositions exist.
