Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494210, here are decompositions:

19 + 494191 = 494210
43 + 494167 = 494210
103 + 494107 = 494210
109 + 494101 = 494210
127 + 494083 = 494210
181 + 494029 = 494210
271 + 493939 = 494210
313 + 493897 = 494210

Showing the first eight; more decompositions exist.
