Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5580, here are decompositions:
- 7 + 5573 = 5580
- 11 + 5569 = 5580
- 17 + 5563 = 5580
- 23 + 5557 = 5580
- 53 + 5527 = 5580
- 59 + 5521 = 5580
- 61 + 5519 = 5580
- 73 + 5507 = 5580
Showing the first eight; more decompositions exist.
