Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707580, here are decompositions:

43 + 8707537 = 8707580
103 + 8707477 = 8707580
151 + 8707429 = 8707580
223 + 8707357 = 8707580
229 + 8707351 = 8707580
307 + 8707273 = 8707580
373 + 8707207 = 8707580
397 + 8707183 = 8707580

Showing the first eight; more decompositions exist.
