Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467254, here are decompositions:

3 + 31467251 = 31467254
73 + 31467181 = 31467254
97 + 31467157 = 31467254
127 + 31467127 = 31467254
151 + 31467103 = 31467254
277 + 31466977 = 31467254
397 + 31466857 = 31467254
433 + 31466821 = 31467254

Showing the first eight; more decompositions exist.
