Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490372, here are decompositions:

5 + 490367 = 490372
59 + 490313 = 490372
89 + 490283 = 490372
101 + 490271 = 490372
131 + 490241 = 490372
149 + 490223 = 490372
251 + 490121 = 490372
269 + 490103 = 490372

Showing the first eight; more decompositions exist.
