Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019904, here are decompositions:

5 + 1019899 = 1019904
31 + 1019873 = 1019904
43 + 1019861 = 1019904
47 + 1019857 = 1019904
103 + 1019801 = 1019904
157 + 1019747 = 1019904
163 + 1019741 = 1019904
173 + 1019731 = 1019904

Showing the first eight; more decompositions exist.
