Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30926, here are decompositions:
- 67 + 30859 = 30926
- 73 + 30853 = 30926
- 97 + 30829 = 30926
- 109 + 30817 = 30926
- 163 + 30763 = 30926
- 199 + 30727 = 30926
- 223 + 30703 = 30926
- 229 + 30697 = 30926
Showing the first eight; more decompositions exist.
