Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526356, here are decompositions:
- 5 + 31526351 = 31526356
- 83 + 31526273 = 31526356
- 149 + 31526207 = 31526356
- 167 + 31526189 = 31526356
- 269 + 31526087 = 31526356
- 293 + 31526063 = 31526356
- 443 + 31525913 = 31526356
- 467 + 31525889 = 31526356
Showing the first eight; more decompositions exist.
