Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467398, here are decompositions:

31 + 31467367 = 31467398
97 + 31467301 = 31467398
139 + 31467259 = 31467398
199 + 31467199 = 31467398
229 + 31467169 = 31467398
241 + 31467157 = 31467398
271 + 31467127 = 31467398
331 + 31467067 = 31467398

Showing the first eight; more decompositions exist.
