Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453016, here are decompositions:

43 + 31452973 = 31453016
73 + 31452943 = 31453016
157 + 31452859 = 31453016
223 + 31452793 = 31453016
277 + 31452739 = 31453016
349 + 31452667 = 31453016
367 + 31452649 = 31453016
409 + 31452607 = 31453016

Showing the first eight; more decompositions exist.
