Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11520, here are decompositions:
- 17 + 11503 = 11520
- 23 + 11497 = 11520
- 29 + 11491 = 11520
- 31 + 11489 = 11520
- 37 + 11483 = 11520
- 53 + 11467 = 11520
- 73 + 11447 = 11520
- 83 + 11437 = 11520
Showing the first eight; more decompositions exist.
