Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87386, here are decompositions:

3 + 87383 = 87386
73 + 87313 = 87386
109 + 87277 = 87386
163 + 87223 = 87386
199 + 87187 = 87386
283 + 87103 = 87386
337 + 87049 = 87386
349 + 87037 = 87386

Showing the first eight; more decompositions exist.
