Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40004, here are decompositions:

67 + 39937 = 40004
103 + 39901 = 40004
127 + 39877 = 40004
157 + 39847 = 40004
163 + 39841 = 40004
271 + 39733 = 40004
277 + 39727 = 40004
337 + 39667 = 40004

Showing the first eight; more decompositions exist.
