Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017200, here are decompositions:

7 + 1017193 = 1017200
43 + 1017157 = 1017200
61 + 1017139 = 1017200
103 + 1017097 = 1017200
139 + 1017061 = 1017200
157 + 1017043 = 1017200
193 + 1017007 = 1017200
229 + 1016971 = 1017200

Showing the first eight; more decompositions exist.
