Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467344, here are decompositions:

43 + 31467301 = 31467344
163 + 31467181 = 31467344
211 + 31467133 = 31467344
241 + 31467103 = 31467344
277 + 31467067 = 31467344
367 + 31466977 = 31467344
487 + 31466857 = 31467344
523 + 31466821 = 31467344

Showing the first eight; more decompositions exist.
