Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454484, here are decompositions:

23 + 31454461 = 31454484
43 + 31454441 = 31454484
53 + 31454431 = 31454484
101 + 31454383 = 31454484
107 + 31454377 = 31454484
163 + 31454321 = 31454484
263 + 31454221 = 31454484
283 + 31454201 = 31454484

Showing the first eight; more decompositions exist.
