Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40318, here are decompositions:
- 29 + 40289 = 40318
- 41 + 40277 = 40318
- 149 + 40169 = 40318
- 167 + 40151 = 40318
- 191 + 40127 = 40318
- 281 + 40037 = 40318
- 347 + 39971 = 40318
- 389 + 39929 = 40318
Showing the first eight; more decompositions exist.
