Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454132, here are decompositions:

79 + 31454053 = 31454132
109 + 31454023 = 31454132
139 + 31453993 = 31454132
163 + 31453969 = 31454132
223 + 31453909 = 31454132
349 + 31453783 = 31454132
421 + 31453711 = 31454132
433 + 31453699 = 31454132

Showing the first eight; more decompositions exist.
