Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454176, here are decompositions:

29 + 31454147 = 31454176
53 + 31454123 = 31454176
59 + 31454117 = 31454176
179 + 31453997 = 31454176
233 + 31453943 = 31454176
293 + 31453883 = 31454176
353 + 31453823 = 31454176
443 + 31453733 = 31454176

Showing the first eight; more decompositions exist.
