Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527386, here are decompositions:
- 43 + 31527343 = 31527386
- 109 + 31527277 = 31527386
- 139 + 31527247 = 31527386
- 193 + 31527193 = 31527386
- 229 + 31527157 = 31527386
- 277 + 31527109 = 31527386
- 433 + 31526953 = 31527386
- 487 + 31526899 = 31527386
Showing the first eight; more decompositions exist.
