Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019970, here are decompositions:

43 + 1019927 = 1019970
67 + 1019903 = 1019970
71 + 1019899 = 1019970
97 + 1019873 = 1019970
109 + 1019861 = 1019970
113 + 1019857 = 1019970
131 + 1019839 = 1019970
151 + 1019819 = 1019970

Showing the first eight; more decompositions exist.
