Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045078, here are decompositions:

17 + 1045061 = 1045078
107 + 1044971 = 1045078
137 + 1044941 = 1045078
227 + 1044851 = 1045078
239 + 1044839 = 1045078
269 + 1044809 = 1045078
311 + 1044767 = 1045078
317 + 1044761 = 1045078

Showing the first eight; more decompositions exist.
