Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454924, here are decompositions:

43 + 31454881 = 31454924
97 + 31454827 = 31454924
223 + 31454701 = 31454924
271 + 31454653 = 31454924
337 + 31454587 = 31454924
463 + 31454461 = 31454924
541 + 31454383 = 31454924
547 + 31454377 = 31454924

Showing the first eight; more decompositions exist.
