Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87002, here are decompositions:

43 + 86959 = 87002
73 + 86929 = 87002
79 + 86923 = 87002
151 + 86851 = 87002
283 + 86719 = 87002
313 + 86689 = 87002
373 + 86629 = 87002
463 + 86539 = 87002

Showing the first eight; more decompositions exist.
