Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87236, here are decompositions:

13 + 87223 = 87236
103 + 87133 = 87236
199 + 87037 = 87236
223 + 87013 = 87236
277 + 86959 = 87236
307 + 86929 = 87236
313 + 86923 = 87236
367 + 86869 = 87236

Showing the first eight; more decompositions exist.
