Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536888, here are decompositions:
- 17 + 31536871 = 31536888
- 41 + 31536847 = 31536888
- 59 + 31536829 = 31536888
- 67 + 31536821 = 31536888
- 157 + 31536731 = 31536888
- 181 + 31536707 = 31536888
- 191 + 31536697 = 31536888
- 281 + 31536607 = 31536888
Showing the first eight; more decompositions exist.
