Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003072, here are decompositions:

23 + 1003049 = 1003072
53 + 1003019 = 1003072
71 + 1003001 = 1003072
173 + 1002899 = 1003072
179 + 1002893 = 1003072
251 + 1002821 = 1003072
263 + 1002809 = 1003072
353 + 1002719 = 1003072

Showing the first eight; more decompositions exist.
