Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123804, here are decompositions:

13 + 123791 = 123804
17 + 123787 = 123804
47 + 123757 = 123804
67 + 123737 = 123804
71 + 123733 = 123804
73 + 123731 = 123804
97 + 123707 = 123804
103 + 123701 = 123804

Showing the first eight; more decompositions exist.
