Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87576, here are decompositions:

17 + 87559 = 87576
19 + 87557 = 87576
23 + 87553 = 87576
29 + 87547 = 87576
37 + 87539 = 87576
53 + 87523 = 87576
59 + 87517 = 87576
67 + 87509 = 87576

Showing the first eight; more decompositions exist.
