Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87380, here are decompositions:

43 + 87337 = 87380
67 + 87313 = 87380
103 + 87277 = 87380
127 + 87253 = 87380
157 + 87223 = 87380
193 + 87187 = 87380
199 + 87181 = 87380
229 + 87151 = 87380

Showing the first eight; more decompositions exist.
