Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87182, here are decompositions:

3 + 87179 = 87182
31 + 87151 = 87182
61 + 87121 = 87182
79 + 87103 = 87182
223 + 86959 = 87182
313 + 86869 = 87182
331 + 86851 = 87182
439 + 86743 = 87182

Showing the first eight; more decompositions exist.
