Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697580, here are decompositions:

29 + 8697551 = 8697580
41 + 8697539 = 8697580
71 + 8697509 = 8697580
173 + 8697407 = 8697580
191 + 8697389 = 8697580
317 + 8697263 = 8697580
347 + 8697233 = 8697580
467 + 8697113 = 8697580

Showing the first eight; more decompositions exist.
