Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977904, here are decompositions:

7 + 977897 = 977904
23 + 977881 = 977904
43 + 977861 = 977904
73 + 977831 = 977904
101 + 977803 = 977904
113 + 977791 = 977904
157 + 977747 = 977904
181 + 977723 = 977904

Showing the first eight; more decompositions exist.
