Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009904, here are decompositions:

3 + 1009901 = 1009904
31 + 1009873 = 1009904
61 + 1009843 = 1009904
67 + 1009837 = 1009904
97 + 1009807 = 1009904
157 + 1009747 = 1009904
163 + 1009741 = 1009904
277 + 1009627 = 1009904

Showing the first eight; more decompositions exist.
