Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40672, here are decompositions:
- 89 + 40583 = 40672
- 113 + 40559 = 40672
- 173 + 40499 = 40672
- 179 + 40493 = 40672
- 239 + 40433 = 40672
- 311 + 40361 = 40672
- 383 + 40289 = 40672
- 389 + 40283 = 40672
Showing the first eight; more decompositions exist.
