Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527506, here are decompositions:
- 7 + 31527499 = 31527506
- 163 + 31527343 = 31527506
- 229 + 31527277 = 31527506
- 313 + 31527193 = 31527506
- 349 + 31527157 = 31527506
- 397 + 31527109 = 31527506
- 607 + 31526899 = 31527506
- 613 + 31526893 = 31527506
Showing the first eight; more decompositions exist.
