Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87558, here are decompositions:

5 + 87553 = 87558
11 + 87547 = 87558
17 + 87541 = 87558
19 + 87539 = 87558
41 + 87517 = 87558
47 + 87511 = 87558
67 + 87491 = 87558
131 + 87427 = 87558

Showing the first eight; more decompositions exist.
