Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454246, here are decompositions:

97 + 31454149 = 31454246
163 + 31454083 = 31454246
193 + 31454053 = 31454246
223 + 31454023 = 31454246
277 + 31453969 = 31454246
337 + 31453909 = 31454246
349 + 31453897 = 31454246
367 + 31453879 = 31454246

Showing the first eight; more decompositions exist.
