Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7620, here are decompositions:

13 + 7607 = 7620
17 + 7603 = 7620
29 + 7591 = 7620
31 + 7589 = 7620
37 + 7583 = 7620
43 + 7577 = 7620
47 + 7573 = 7620
59 + 7561 = 7620

Showing the first eight; more decompositions exist.
