Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490250, here are decompositions:

3 + 490247 = 490250
43 + 490207 = 490250
67 + 490183 = 490250
139 + 490111 = 490250
193 + 490057 = 490250
307 + 489943 = 490250
337 + 489913 = 490250
349 + 489901 = 490250

Showing the first eight; more decompositions exist.
