Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494222, here are decompositions:

31 + 494191 = 494222
139 + 494083 = 494222
181 + 494041 = 494222
193 + 494029 = 494222
199 + 494023 = 494222
229 + 493993 = 494222
283 + 493939 = 494222
349 + 493873 = 494222

Showing the first eight; more decompositions exist.
