Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042998, here are decompositions:

37 + 1042961 = 1042998
67 + 1042931 = 1042998
97 + 1042901 = 1042998
101 + 1042897 = 1042998
137 + 1042861 = 1042998
149 + 1042849 = 1042998
179 + 1042819 = 1042998
199 + 1042799 = 1042998

Showing the first eight; more decompositions exist.
