Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40286, here are decompositions:
- 3 + 40283 = 40286
- 73 + 40213 = 40286
- 97 + 40189 = 40286
- 109 + 40177 = 40286
- 157 + 40129 = 40286
- 163 + 40123 = 40286
- 193 + 40093 = 40286
- 199 + 40087 = 40286
Showing the first eight; more decompositions exist.
