Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101904, here are decompositions:

13 + 101891 = 101904
31 + 101873 = 101904
41 + 101863 = 101904
67 + 101837 = 101904
71 + 101833 = 101904
97 + 101807 = 101904
107 + 101797 = 101904
157 + 101747 = 101904

Showing the first eight; more decompositions exist.
