Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10404, here are decompositions:

5 + 10399 = 10404
13 + 10391 = 10404
47 + 10357 = 10404
61 + 10343 = 10404
67 + 10337 = 10404
71 + 10333 = 10404
73 + 10331 = 10404
83 + 10321 = 10404

Showing the first eight; more decompositions exist.
