Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467438, here are decompositions:

5 + 31467433 = 31467438
7 + 31467431 = 31467438
19 + 31467419 = 31467438
71 + 31467367 = 31467438
109 + 31467329 = 31467438
127 + 31467311 = 31467438
137 + 31467301 = 31467438
179 + 31467259 = 31467438

Showing the first eight; more decompositions exist.
