Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467338, here are decompositions:

37 + 31467301 = 31467338
79 + 31467259 = 31467338
109 + 31467229 = 31467338
139 + 31467199 = 31467338
157 + 31467181 = 31467338
181 + 31467157 = 31467338
211 + 31467127 = 31467338
271 + 31467067 = 31467338

Showing the first eight; more decompositions exist.
