Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51904, here are decompositions:

5 + 51899 = 51904
11 + 51893 = 51904
101 + 51803 = 51904
107 + 51797 = 51904
137 + 51767 = 51904
191 + 51713 = 51904
257 + 51647 = 51904
311 + 51593 = 51904

Showing the first eight; more decompositions exist.
