Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051720, here are decompositions:

3 + 1051717 = 1051720
11 + 1051709 = 1051720
23 + 1051697 = 1051720
71 + 1051649 = 1051720
101 + 1051619 = 1051720
113 + 1051607 = 1051720
149 + 1051571 = 1051720
167 + 1051553 = 1051720

Showing the first eight; more decompositions exist.
