Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490394, here are decompositions:

127 + 490267 = 490394
193 + 490201 = 490394
211 + 490183 = 490394
277 + 490117 = 490394
283 + 490111 = 490394
337 + 490057 = 490394
433 + 489961 = 490394
523 + 489871 = 490394

Showing the first eight; more decompositions exist.
