Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979904, here are decompositions:

31 + 979873 = 979904
73 + 979831 = 979904
97 + 979807 = 979904
157 + 979747 = 979904
337 + 979567 = 979904
433 + 979471 = 979904
571 + 979333 = 979904
577 + 979327 = 979904

Showing the first eight; more decompositions exist.
