Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40204, here are decompositions:
- 11 + 40193 = 40204
- 41 + 40163 = 40204
- 53 + 40151 = 40204
- 167 + 40037 = 40204
- 173 + 40031 = 40204
- 191 + 40013 = 40204
- 233 + 39971 = 40204
- 251 + 39953 = 40204
Showing the first eight; more decompositions exist.
