Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87582, here are decompositions:

23 + 87559 = 87582
29 + 87553 = 87582
41 + 87541 = 87582
43 + 87539 = 87582
59 + 87523 = 87582
71 + 87511 = 87582
73 + 87509 = 87582
101 + 87481 = 87582

Showing the first eight; more decompositions exist.
