Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479642, here are decompositions:

3 + 479639 = 479642
13 + 479629 = 479642
19 + 479623 = 479642
43 + 479599 = 479642
61 + 479581 = 479642
73 + 479569 = 479642
109 + 479533 = 479642
181 + 479461 = 479642

Showing the first eight; more decompositions exist.
