Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494240, here are decompositions:

3 + 494237 = 494240
73 + 494167 = 494240
139 + 494101 = 494240
157 + 494083 = 494240
163 + 494077 = 494240
199 + 494041 = 494240
211 + 494029 = 494240
367 + 493873 = 494240

Showing the first eight; more decompositions exist.
