Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40104, here are decompositions:

5 + 40099 = 40104
11 + 40093 = 40104
17 + 40087 = 40104
41 + 40063 = 40104
67 + 40037 = 40104
73 + 40031 = 40104
151 + 39953 = 40104
167 + 39937 = 40104

Showing the first eight; more decompositions exist.
