Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453214, here are decompositions:

7 + 31453207 = 31453214
43 + 31453171 = 31453214
73 + 31453141 = 31453214
193 + 31453021 = 31453214
241 + 31452973 = 31453214
271 + 31452943 = 31453214
313 + 31452901 = 31453214
421 + 31452793 = 31453214

Showing the first eight; more decompositions exist.
