Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486642, here are decompositions:

5 + 486637 = 486642
41 + 486601 = 486642
53 + 486589 = 486642
59 + 486583 = 486642
73 + 486569 = 486642
83 + 486559 = 486642
103 + 486539 = 486642
131 + 486511 = 486642

Showing the first eight; more decompositions exist.
