Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87392, here are decompositions:

79 + 87313 = 87392
139 + 87253 = 87392
181 + 87211 = 87392
211 + 87181 = 87392
241 + 87151 = 87392
271 + 87121 = 87392
379 + 87013 = 87392
433 + 86959 = 87392

Showing the first eight; more decompositions exist.
