Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030280, here are decompositions:

61 + 1030219 = 1030280
67 + 1030213 = 1030280
79 + 1030201 = 1030280
127 + 1030153 = 1030280
211 + 1030069 = 1030280
241 + 1030039 = 1030280
313 + 1029967 = 1030280
337 + 1029943 = 1030280

Showing the first eight; more decompositions exist.
