Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453046, here are decompositions:

7 + 31453039 = 31453046
73 + 31452973 = 31453046
103 + 31452943 = 31453046
277 + 31452769 = 31453046
283 + 31452763 = 31453046
307 + 31452739 = 31453046
379 + 31452667 = 31453046
397 + 31452649 = 31453046

Showing the first eight; more decompositions exist.
