Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11172, here are decompositions:
- 11 + 11161 = 11172
- 13 + 11159 = 11172
- 23 + 11149 = 11172
- 41 + 11131 = 11172
- 53 + 11119 = 11172
- 59 + 11113 = 11172
- 79 + 11093 = 11172
- 89 + 11083 = 11172
Showing the first eight; more decompositions exist.
