Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87356, here are decompositions:

19 + 87337 = 87356
43 + 87313 = 87356
79 + 87277 = 87356
103 + 87253 = 87356
223 + 87133 = 87356
307 + 87049 = 87356
397 + 86959 = 87356
433 + 86923 = 87356

Showing the first eight; more decompositions exist.
