Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939040, here are decompositions:

29 + 939011 = 939040
59 + 938981 = 939040
71 + 938969 = 939040
101 + 938939 = 939040
197 + 938843 = 939040
233 + 938807 = 939040
293 + 938747 = 939040
359 + 938681 = 939040

Showing the first eight; more decompositions exist.
