Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87206, here are decompositions:

19 + 87187 = 87206
73 + 87133 = 87206
103 + 87103 = 87206
157 + 87049 = 87206
193 + 87013 = 87206
277 + 86929 = 87206
283 + 86923 = 87206
337 + 86869 = 87206

Showing the first eight; more decompositions exist.
