Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42580, here are decompositions:

3 + 42577 = 42580
11 + 42569 = 42580
23 + 42557 = 42580
47 + 42533 = 42580
71 + 42509 = 42580
89 + 42491 = 42580
107 + 42473 = 42580
113 + 42467 = 42580

Showing the first eight; more decompositions exist.
