Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11530, here are decompositions:
- 3 + 11527 = 11530
- 11 + 11519 = 11530
- 41 + 11489 = 11530
- 47 + 11483 = 11530
- 59 + 11471 = 11530
- 83 + 11447 = 11530
- 107 + 11423 = 11530
- 131 + 11399 = 11530
Showing the first eight; more decompositions exist.
