Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698580, here are decompositions:

31 + 8698549 = 8698580
181 + 8698399 = 8698580
211 + 8698369 = 8698580
283 + 8698297 = 8698580
367 + 8698213 = 8698580
487 + 8698093 = 8698580
571 + 8698009 = 8698580
607 + 8697973 = 8698580

Showing the first eight; more decompositions exist.
