Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007428, here are decompositions:

11 + 1007417 = 1007428
41 + 1007387 = 1007428
47 + 1007381 = 1007428
89 + 1007339 = 1007428
131 + 1007297 = 1007428
179 + 1007249 = 1007428
197 + 1007231 = 1007428
311 + 1007117 = 1007428

Showing the first eight; more decompositions exist.
