Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490928, here are decompositions:

7 + 490921 = 490928
37 + 490891 = 490928
79 + 490849 = 490928
157 + 490771 = 490928
337 + 490591 = 490928
349 + 490579 = 490928
379 + 490549 = 490928
409 + 490519 = 490928

Showing the first eight; more decompositions exist.
