Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77580, here are decompositions:

7 + 77573 = 77580
11 + 77569 = 77580
17 + 77563 = 77580
23 + 77557 = 77580
29 + 77551 = 77580
31 + 77549 = 77580
37 + 77543 = 77580
53 + 77527 = 77580

Showing the first eight; more decompositions exist.
