Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527666, here are decompositions:
- 7 + 31527659 = 31527666
- 83 + 31527583 = 31527666
- 89 + 31527577 = 31527666
- 97 + 31527569 = 31527666
- 167 + 31527499 = 31527666
- 277 + 31527389 = 31527666
- 349 + 31527317 = 31527666
- 389 + 31527277 = 31527666
Showing the first eight; more decompositions exist.
