Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756580, here are decompositions:

13 + 8756567 = 8756580
23 + 8756557 = 8756580
29 + 8756551 = 8756580
47 + 8756533 = 8756580
61 + 8756519 = 8756580
71 + 8756509 = 8756580
73 + 8756507 = 8756580
109 + 8756471 = 8756580

Showing the first eight; more decompositions exist.
