Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464840, here are decompositions:

31 + 464809 = 464840
37 + 464803 = 464840
67 + 464773 = 464840
73 + 464767 = 464840
193 + 464647 = 464840
223 + 464617 = 464840
283 + 464557 = 464840
373 + 464467 = 464840

Showing the first eight; more decompositions exist.
