Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87540, here are decompositions:

17 + 87523 = 87540
23 + 87517 = 87540
29 + 87511 = 87540
31 + 87509 = 87540
59 + 87481 = 87540
67 + 87473 = 87540
97 + 87443 = 87540
107 + 87433 = 87540

Showing the first eight; more decompositions exist.
