Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454318, here are decompositions:

97 + 31454221 = 31454318
127 + 31454191 = 31454318
157 + 31454161 = 31454318
241 + 31454077 = 31454318
349 + 31453969 = 31454318
409 + 31453909 = 31454318
421 + 31453897 = 31454318
439 + 31453879 = 31454318

Showing the first eight; more decompositions exist.
