Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715580, here are decompositions:

131 + 8715449 = 8715580
149 + 8715431 = 8715580
179 + 8715401 = 8715580
197 + 8715383 = 8715580
233 + 8715347 = 8715580
257 + 8715323 = 8715580
311 + 8715269 = 8715580
317 + 8715263 = 8715580

Showing the first eight; more decompositions exist.
