Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031200, here are decompositions:

11 + 1031189 = 1031200
59 + 1031141 = 1031200
83 + 1031117 = 1031200
197 + 1031003 = 1031200
251 + 1030949 = 1031200
281 + 1030919 = 1031200
311 + 1030889 = 1031200
353 + 1030847 = 1031200

Showing the first eight; more decompositions exist.
