Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490370, here are decompositions:

3 + 490367 = 490370
31 + 490339 = 490370
61 + 490309 = 490370
103 + 490267 = 490370
163 + 490207 = 490370
211 + 490159 = 490370
313 + 490057 = 490370
337 + 490033 = 490370

Showing the first eight; more decompositions exist.
