Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490388, here are decompositions:

79 + 490309 = 490388
139 + 490249 = 490388
181 + 490207 = 490388
229 + 490159 = 490388
271 + 490117 = 490388
277 + 490111 = 490388
331 + 490057 = 490388
487 + 489901 = 490388

Showing the first eight; more decompositions exist.
