Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453826, here are decompositions:

3 + 31453823 = 31453826
13 + 31453813 = 31453826
43 + 31453783 = 31453826
127 + 31453699 = 31453826
379 + 31453447 = 31453826
433 + 31453393 = 31453826
577 + 31453249 = 31453826
619 + 31453207 = 31453826

Showing the first eight; more decompositions exist.
