Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35712, here are decompositions:
- 41 + 35671 = 35712
- 109 + 35603 = 35712
- 139 + 35573 = 35712
- 179 + 35533 = 35712
- 181 + 35531 = 35712
- 191 + 35521 = 35712
- 251 + 35461 = 35712
- 263 + 35449 = 35712
Showing the first eight; more decompositions exist.
