Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456434, here are decompositions:

5 + 31456429 = 31456434
73 + 31456361 = 31456434
103 + 31456331 = 31456434
157 + 31456277 = 31456434
193 + 31456241 = 31456434
197 + 31456237 = 31456434
241 + 31456193 = 31456434
271 + 31456163 = 31456434

Showing the first eight; more decompositions exist.
