Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454048, here are decompositions:

79 + 31453969 = 31454048
139 + 31453909 = 31454048
151 + 31453897 = 31454048
181 + 31453867 = 31454048
337 + 31453711 = 31454048
349 + 31453699 = 31454048
397 + 31453651 = 31454048
541 + 31453507 = 31454048

Showing the first eight; more decompositions exist.
