Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6580, here are decompositions:
- 3 + 6577 = 6580
- 11 + 6569 = 6580
- 17 + 6563 = 6580
- 29 + 6551 = 6580
- 59 + 6521 = 6580
- 89 + 6491 = 6580
- 107 + 6473 = 6580
- 131 + 6449 = 6580
Showing the first eight; more decompositions exist.
