Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11556, here are decompositions:
- 5 + 11551 = 11556
- 7 + 11549 = 11556
- 29 + 11527 = 11556
- 37 + 11519 = 11556
- 53 + 11503 = 11556
- 59 + 11497 = 11556
- 67 + 11489 = 11556
- 73 + 11483 = 11556
Showing the first eight; more decompositions exist.
