Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87404, here are decompositions:

67 + 87337 = 87404
127 + 87277 = 87404
151 + 87253 = 87404
181 + 87223 = 87404
193 + 87211 = 87404
223 + 87181 = 87404
271 + 87133 = 87404
283 + 87121 = 87404

Showing the first eight; more decompositions exist.
