Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11156, here are decompositions:
- 7 + 11149 = 11156
- 37 + 11119 = 11156
- 43 + 11113 = 11156
- 73 + 11083 = 11156
- 97 + 11059 = 11156
- 109 + 11047 = 11156
- 163 + 10993 = 11156
- 199 + 10957 = 11156
Showing the first eight; more decompositions exist.
