Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019772, here are decompositions:

31 + 1019741 = 1019772
41 + 1019731 = 1019772
43 + 1019729 = 1019772
59 + 1019713 = 1019772
71 + 1019701 = 1019772
73 + 1019699 = 1019772
79 + 1019693 = 1019772
109 + 1019663 = 1019772

Showing the first eight; more decompositions exist.
