Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456464, here are decompositions:

23 + 31456441 = 31456464
103 + 31456361 = 31456464
173 + 31456291 = 31456464
223 + 31456241 = 31456464
227 + 31456237 = 31456464
271 + 31456193 = 31456464
397 + 31456067 = 31456464
443 + 31456021 = 31456464

Showing the first eight; more decompositions exist.
