Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40416, here are decompositions:
- 29 + 40387 = 40416
- 59 + 40357 = 40416
- 73 + 40343 = 40416
- 127 + 40289 = 40416
- 139 + 40277 = 40416
- 163 + 40253 = 40416
- 179 + 40237 = 40416
- 223 + 40193 = 40416
Showing the first eight; more decompositions exist.
