Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11656, here are decompositions:
- 23 + 11633 = 11656
- 59 + 11597 = 11656
- 107 + 11549 = 11656
- 137 + 11519 = 11656
- 167 + 11489 = 11656
- 173 + 11483 = 11656
- 233 + 11423 = 11656
- 257 + 11399 = 11656
Showing the first eight; more decompositions exist.
