Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87460, here are decompositions:

17 + 87443 = 87460
53 + 87407 = 87460
101 + 87359 = 87460
137 + 87323 = 87460
167 + 87293 = 87460
179 + 87281 = 87460
239 + 87221 = 87460
281 + 87179 = 87460

Showing the first eight; more decompositions exist.
