Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494138, here are decompositions:

31 + 494107 = 494138
37 + 494101 = 494138
61 + 494077 = 494138
97 + 494041 = 494138
109 + 494029 = 494138
199 + 493939 = 494138
241 + 493897 = 494138
331 + 493807 = 494138

Showing the first eight; more decompositions exist.
