Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40904, here are decompositions:

7 + 40897 = 40904
37 + 40867 = 40904
103 + 40801 = 40904
211 + 40693 = 40904
277 + 40627 = 40904
307 + 40597 = 40904
313 + 40591 = 40904
373 + 40531 = 40904

Showing the first eight; more decompositions exist.
