Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11956, here are decompositions:
- 3 + 11953 = 11956
- 17 + 11939 = 11956
- 23 + 11933 = 11956
- 29 + 11927 = 11956
- 47 + 11909 = 11956
- 53 + 11903 = 11956
- 59 + 11897 = 11956
- 89 + 11867 = 11956
Showing the first eight; more decompositions exist.
