Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142620, here are decompositions:

11 + 142609 = 142620
13 + 142607 = 142620
19 + 142601 = 142620
29 + 142591 = 142620
31 + 142589 = 142620
47 + 142573 = 142620
53 + 142567 = 142620
61 + 142559 = 142620

Showing the first eight; more decompositions exist.
