Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11930, here are decompositions:
- 3 + 11927 = 11930
- 7 + 11923 = 11930
- 43 + 11887 = 11930
- 67 + 11863 = 11930
- 97 + 11833 = 11930
- 103 + 11827 = 11930
- 109 + 11821 = 11930
- 151 + 11779 = 11930
Showing the first eight; more decompositions exist.
