Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11680, here are decompositions:
- 3 + 11677 = 11680
- 23 + 11657 = 11680
- 47 + 11633 = 11680
- 59 + 11621 = 11680
- 83 + 11597 = 11680
- 101 + 11579 = 11680
- 131 + 11549 = 11680
- 191 + 11489 = 11680
Showing the first eight; more decompositions exist.
