Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943904, here are decompositions:

61 + 943843 = 943904
67 + 943837 = 943904
103 + 943801 = 943904
127 + 943777 = 943904
163 + 943741 = 943904
211 + 943693 = 943904
337 + 943567 = 943904
433 + 943471 = 943904

Showing the first eight; more decompositions exist.
