Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 480818, here are decompositions:

31 + 480787 = 480818
157 + 480661 = 480818
277 + 480541 = 480818
367 + 480451 = 480818
409 + 480409 = 480818
439 + 480379 = 480818
661 + 480157 = 480818
727 + 480091 = 480818

Showing the first eight; more decompositions exist.
