Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11240, here are decompositions:
- 43 + 11197 = 11240
- 67 + 11173 = 11240
- 79 + 11161 = 11240
- 109 + 11131 = 11240
- 127 + 11113 = 11240
- 157 + 11083 = 11240
- 181 + 11059 = 11240
- 193 + 11047 = 11240
Showing the first eight; more decompositions exist.
