Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40396, here are decompositions:
- 53 + 40343 = 40396
- 107 + 40289 = 40396
- 113 + 40283 = 40396
- 227 + 40169 = 40396
- 233 + 40163 = 40396
- 269 + 40127 = 40396
- 359 + 40037 = 40396
- 383 + 40013 = 40396
Showing the first eight; more decompositions exist.
