Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011720, here are decompositions:

23 + 1011697 = 1011720
43 + 1011677 = 1011720
53 + 1011667 = 1011720
71 + 1011649 = 1011720
79 + 1011641 = 1011720
89 + 1011631 = 1011720
131 + 1011589 = 1011720
137 + 1011583 = 1011720

Showing the first eight; more decompositions exist.
