Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87620, here are decompositions:

7 + 87613 = 87620
31 + 87589 = 87620
37 + 87583 = 87620
61 + 87559 = 87620
67 + 87553 = 87620
73 + 87547 = 87620
79 + 87541 = 87620
97 + 87523 = 87620

Showing the first eight; more decompositions exist.
