Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87504, here are decompositions:

13 + 87491 = 87504
23 + 87481 = 87504
31 + 87473 = 87504
61 + 87443 = 87504
71 + 87433 = 87504
83 + 87421 = 87504
97 + 87407 = 87504
101 + 87403 = 87504

Showing the first eight; more decompositions exist.
