Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712492, here are decompositions:

71 + 8712421 = 8712492
181 + 8712311 = 8712492
199 + 8712293 = 8712492
211 + 8712281 = 8712492
223 + 8712269 = 8712492
233 + 8712259 = 8712492
263 + 8712229 = 8712492
311 + 8712181 = 8712492

Showing the first eight; more decompositions exist.
