Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667580, here are decompositions:

17 + 8667563 = 8667580
41 + 8667539 = 8667580
59 + 8667521 = 8667580
83 + 8667497 = 8667580
149 + 8667431 = 8667580
167 + 8667413 = 8667580
281 + 8667299 = 8667580
353 + 8667227 = 8667580

Showing the first eight; more decompositions exist.
