Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42404, here are decompositions:

7 + 42397 = 42404
13 + 42391 = 42404
31 + 42373 = 42404
67 + 42337 = 42404
73 + 42331 = 42404
97 + 42307 = 42404
181 + 42223 = 42404
211 + 42193 = 42404

Showing the first eight; more decompositions exist.
