Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045138, here are decompositions:

167 + 1044971 = 1045138
197 + 1044941 = 1045138
359 + 1044779 = 1045138
389 + 1044749 = 1045138
401 + 1044737 = 1045138
449 + 1044689 = 1045138
509 + 1044629 = 1045138
569 + 1044569 = 1045138

Showing the first eight; more decompositions exist.
