Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467258, here are decompositions:

7 + 31467251 = 31467258
29 + 31467229 = 31467258
59 + 31467199 = 31467258
89 + 31467169 = 31467258
101 + 31467157 = 31467258
131 + 31467127 = 31467258
191 + 31467067 = 31467258
269 + 31466989 = 31467258

Showing the first eight; more decompositions exist.
