Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26580, here are decompositions:
- 7 + 26573 = 26580
- 19 + 26561 = 26580
- 23 + 26557 = 26580
- 41 + 26539 = 26580
- 67 + 26513 = 26580
- 79 + 26501 = 26580
- 83 + 26497 = 26580
- 101 + 26479 = 26580
Showing the first eight; more decompositions exist.
