Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40372, here are decompositions:
- 11 + 40361 = 40372
- 29 + 40343 = 40372
- 83 + 40289 = 40372
- 89 + 40283 = 40372
- 131 + 40241 = 40372
- 179 + 40193 = 40372
- 359 + 40013 = 40372
- 383 + 39989 = 40372
Showing the first eight; more decompositions exist.
