Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87584, here are decompositions:

31 + 87553 = 87584
37 + 87547 = 87584
43 + 87541 = 87584
61 + 87523 = 87584
67 + 87517 = 87584
73 + 87511 = 87584
103 + 87481 = 87584
151 + 87433 = 87584

Showing the first eight; more decompositions exist.
