Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11228, here are decompositions:
- 31 + 11197 = 11228
- 67 + 11161 = 11228
- 79 + 11149 = 11228
- 97 + 11131 = 11228
- 109 + 11119 = 11228
- 157 + 11071 = 11228
- 181 + 11047 = 11228
- 241 + 10987 = 11228
Showing the first eight; more decompositions exist.
