Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490432, here are decompositions:

11 + 490421 = 490432
149 + 490283 = 490432
191 + 490241 = 490432
263 + 490169 = 490432
281 + 490151 = 490432
311 + 490121 = 490432
401 + 490031 = 490432
431 + 490001 = 490432

Showing the first eight; more decompositions exist.
