Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029200, here are decompositions:

43 + 1029157 = 1029200
61 + 1029139 = 1029200
97 + 1029103 = 1029200
163 + 1029037 = 1029200
199 + 1029001 = 1029200
307 + 1028893 = 1029200
397 + 1028803 = 1029200
439 + 1028761 = 1029200

Showing the first eight; more decompositions exist.
