Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133978, here are decompositions:
- 11 + 133967 = 133978
- 29 + 133949 = 133978
- 59 + 133919 = 133978
- 101 + 133877 = 133978
- 167 + 133811 = 133978
- 197 + 133781 = 133978
- 269 + 133709 = 133978
- 281 + 133697 = 133978
Showing the first eight; more decompositions exist.
