Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87588, here are decompositions:

5 + 87583 = 87588
29 + 87559 = 87588
31 + 87557 = 87588
41 + 87547 = 87588
47 + 87541 = 87588
71 + 87517 = 87588
79 + 87509 = 87588
97 + 87491 = 87588

Showing the first eight; more decompositions exist.
