Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454534, here are decompositions:

37 + 31454497 = 31454534
73 + 31454461 = 31454534
103 + 31454431 = 31454534
151 + 31454383 = 31454534
157 + 31454377 = 31454534
271 + 31454263 = 31454534
313 + 31454221 = 31454534
337 + 31454197 = 31454534

Showing the first eight; more decompositions exist.
