Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494830, here are decompositions:

41 + 494789 = 494830
47 + 494783 = 494830
71 + 494759 = 494830
107 + 494723 = 494830
131 + 494699 = 494830
137 + 494693 = 494830
179 + 494651 = 494830
191 + 494639 = 494830

Showing the first eight; more decompositions exist.
