Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454524, here are decompositions:

11 + 31454513 = 31454524
41 + 31454483 = 31454524
83 + 31454441 = 31454524
173 + 31454351 = 31454524
401 + 31454123 = 31454524
443 + 31454081 = 31454524
593 + 31453931 = 31454524
641 + 31453883 = 31454524

Showing the first eight; more decompositions exist.
