Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40356, here are decompositions:
- 5 + 40351 = 40356
- 13 + 40343 = 40356
- 67 + 40289 = 40356
- 73 + 40283 = 40356
- 79 + 40277 = 40356
- 103 + 40253 = 40356
- 163 + 40193 = 40356
- 167 + 40189 = 40356
Showing the first eight; more decompositions exist.
