Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494238, here are decompositions:

47 + 494191 = 494238
71 + 494167 = 494238
97 + 494141 = 494238
109 + 494129 = 494238
131 + 494107 = 494238
137 + 494101 = 494238
197 + 494041 = 494238
271 + 493967 = 494238

Showing the first eight; more decompositions exist.
