Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042938, here are decompositions:

7 + 1042931 = 1042938
37 + 1042901 = 1042938
41 + 1042897 = 1042938
89 + 1042849 = 1042938
101 + 1042837 = 1042938
109 + 1042829 = 1042938
139 + 1042799 = 1042938
157 + 1042781 = 1042938

Showing the first eight; more decompositions exist.
