Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40230, here are decompositions:
- 17 + 40213 = 40230
- 37 + 40193 = 40230
- 41 + 40189 = 40230
- 53 + 40177 = 40230
- 61 + 40169 = 40230
- 67 + 40163 = 40230
- 79 + 40151 = 40230
- 101 + 40129 = 40230
Showing the first eight; more decompositions exist.
