Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042902, here are decompositions:

5 + 1042897 = 1042902
41 + 1042861 = 1042902
53 + 1042849 = 1042902
73 + 1042829 = 1042902
83 + 1042819 = 1042902
103 + 1042799 = 1042902
193 + 1042709 = 1042902
199 + 1042703 = 1042902

Showing the first eight; more decompositions exist.
