Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453004, here are decompositions:

31 + 31452973 = 31453004
61 + 31452943 = 31453004
103 + 31452901 = 31453004
211 + 31452793 = 31453004
241 + 31452763 = 31453004
277 + 31452727 = 31453004
283 + 31452721 = 31453004
337 + 31452667 = 31453004

Showing the first eight; more decompositions exist.
