Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467396, here are decompositions:

7 + 31467389 = 31467396
29 + 31467367 = 31467396
67 + 31467329 = 31467396
137 + 31467259 = 31467396
167 + 31467229 = 31467396
193 + 31467203 = 31467396
197 + 31467199 = 31467396
227 + 31467169 = 31467396

Showing the first eight; more decompositions exist.
