Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453196, here are decompositions:

3 + 31453193 = 31453196
37 + 31453159 = 31453196
157 + 31453039 = 31453196
223 + 31452973 = 31453196
337 + 31452859 = 31453196
367 + 31452829 = 31453196
433 + 31452763 = 31453196
457 + 31452739 = 31453196

Showing the first eight; more decompositions exist.
