Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40078, here are decompositions:
- 41 + 40037 = 40078
- 47 + 40031 = 40078
- 89 + 39989 = 40078
- 107 + 39971 = 40078
- 149 + 39929 = 40078
- 191 + 39887 = 40078
- 239 + 39839 = 40078
- 251 + 39827 = 40078
Showing the first eight; more decompositions exist.
