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.
