Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019928, here are decompositions:

29 + 1019899 = 1019928
67 + 1019861 = 1019928
71 + 1019857 = 1019928
79 + 1019849 = 1019928
89 + 1019839 = 1019928
101 + 1019827 = 1019928
109 + 1019819 = 1019928
127 + 1019801 = 1019928

Showing the first eight; more decompositions exist.
