Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049220, here are decompositions:

19 + 1049201 = 1049220
37 + 1049183 = 1049220
43 + 1049177 = 1049220
47 + 1049173 = 1049220
79 + 1049141 = 1049220
83 + 1049137 = 1049220
89 + 1049131 = 1049220
103 + 1049117 = 1049220

Showing the first eight; more decompositions exist.
