Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740620, here are decompositions:

13 + 8740607 = 8740620
17 + 8740603 = 8740620
29 + 8740591 = 8740620
41 + 8740579 = 8740620
43 + 8740577 = 8740620
59 + 8740561 = 8740620
61 + 8740559 = 8740620
79 + 8740541 = 8740620

Showing the first eight; more decompositions exist.
