Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998156, here are decompositions:

73 + 998083 = 998156
79 + 998077 = 998156
127 + 998029 = 998156
139 + 998017 = 998156
193 + 997963 = 998156
223 + 997933 = 998156
277 + 997879 = 998156
349 + 997807 = 998156

Showing the first eight; more decompositions exist.
