Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11580, here are decompositions:
- 29 + 11551 = 11580
- 31 + 11549 = 11580
- 53 + 11527 = 11580
- 61 + 11519 = 11580
- 83 + 11497 = 11580
- 89 + 11491 = 11580
- 97 + 11483 = 11580
- 109 + 11471 = 11580
Showing the first eight; more decompositions exist.
