Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486842, here are decompositions:

3 + 486839 = 486842
61 + 486781 = 486842
73 + 486769 = 486842
163 + 486679 = 486842
199 + 486643 = 486842
241 + 486601 = 486842
283 + 486559 = 486842
331 + 486511 = 486842

Showing the first eight; more decompositions exist.
