Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454462, here are decompositions:

31 + 31454431 = 31454462
73 + 31454389 = 31454462
79 + 31454383 = 31454462
199 + 31454263 = 31454462
241 + 31454221 = 31454462
271 + 31454191 = 31454462
313 + 31454149 = 31454462
379 + 31454083 = 31454462

Showing the first eight; more decompositions exist.
