Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40412, here are decompositions:
- 61 + 40351 = 40412
- 181 + 40231 = 40412
- 199 + 40213 = 40412
- 223 + 40189 = 40412
- 283 + 40129 = 40412
- 313 + 40099 = 40412
- 349 + 40063 = 40412
- 373 + 40039 = 40412
Showing the first eight; more decompositions exist.
