Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126804, here are decompositions:

23 + 126781 = 126804
43 + 126761 = 126804
47 + 126757 = 126804
53 + 126751 = 126804
61 + 126743 = 126804
71 + 126733 = 126804
101 + 126703 = 126804
113 + 126691 = 126804

Showing the first eight; more decompositions exist.
