Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454086, here are decompositions:

3 + 31454083 = 31454086
5 + 31454081 = 31454086
89 + 31453997 = 31454086
263 + 31453823 = 31454086
353 + 31453733 = 31454086
359 + 31453727 = 31454086
509 + 31453577 = 31454086
557 + 31453529 = 31454086

Showing the first eight; more decompositions exist.
