Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87422, here are decompositions:

19 + 87403 = 87422
109 + 87313 = 87422
199 + 87223 = 87422
211 + 87211 = 87422
241 + 87181 = 87422
271 + 87151 = 87422
373 + 87049 = 87422
409 + 87013 = 87422

Showing the first eight; more decompositions exist.
