Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4580, here are decompositions:

13 + 4567 = 4580
19 + 4561 = 4580
31 + 4549 = 4580
61 + 4519 = 4580
67 + 4513 = 4580
73 + 4507 = 4580
97 + 4483 = 4580
139 + 4441 = 4580

Showing the first eight; more decompositions exist.
