Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454746, here are decompositions:

5 + 31454741 = 31454746
233 + 31454513 = 31454746
263 + 31454483 = 31454746
599 + 31454147 = 31454746
863 + 31453883 = 31454746
1013 + 31453733 = 31454746
1019 + 31453727 = 31454746
1217 + 31453529 = 31454746

Showing the first eight; more decompositions exist.
