Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051620, here are decompositions:

13 + 1051607 = 1051620
19 + 1051601 = 1051620
29 + 1051591 = 1051620
61 + 1051559 = 1051620
67 + 1051553 = 1051620
71 + 1051549 = 1051620
113 + 1051507 = 1051620
139 + 1051481 = 1051620

Showing the first eight; more decompositions exist.
